 # Features
 
+## Use-Cases & Limitations
+
+The _jsii_ toolchain allows developers to author class libraries once in TypeScript, while allowing their customers to
+consume them in various [other languages](#target-languages). This is used for libraries such as the AWS CDK (
+[`aws-cdk-lib`](https://npmjs.com/package/aws-cdk-lib)), and is intended for use in similar contexts: client-side,
+design-time SDKs that do not require long-running processes and is not in the path to serve time-sensitive requests.
+
+Due to limitations of its [runtime architecture](./runtime-architecture.md), _jsii libraries_ for languages other than
+Javascript/TypeScript are best suited for inclusion in short-running processes, outside of performance-sensitive or
+memory-constrained contexts.
+
+While `async` APIs are supported by the _jsii_ type system, support for these should be treated as highly experimental.
+In particular, support in the various [target languages](#target-languages) varies greatly, and users may encounter a
+variety of bugs or surprising behaviors. The current JavaScript-based cross-language interoperability kernel is also
+known to block execution of background micro-tasks when it's waiting for commands from the host process.
+
+The runtime libraries used by _jsii libraries_ are not currently designed for thread safety, and using _jsii libraries_
+in multi-thread contexts is unsupported at the moment.

 #### Asynchronous method invocation
 
+!!! bug "Largely un-tested"
+    Asynchronous operations are only partially supported in the various target languages, and is currently not widely

+    may run into usability issues, unexpected bugs, or surprising behaviors when using async.

 The `invoke` call can only be used to invoke _synchronous_ methods. In order to invoke _asynchronous_ methods, the

-the first `begin` call), and until it has completed all asynchronous operations (after all `begin` class are matched
-with an `end` call), no _synchronous_ operation (including synchronous callbacks) may be initiated.

-# Soft-Reserved Words
+!!! danger "`#!ts Pick<T, Keys>` and `#!ts Omit<T, Keys>`"
+    Users are often tempted to use `#!ts Pick<T, Keys>` and `#!ts Omit<T, Keys>` when creating higher level abstractions
+    of types exposed by their dependencies, and they want to expose all configuration options from the upstream
+    implementation except for some specific properties which are determined fully by the new abstraction.
+
+    `#!ts Pick<T, Keys>` and `#!ts Omit<T, Keys>` are not supported as they would result in open-ended implementation
+    requirements to exist in languages such as **Java** and **C#** where such things are not possible.
+
+    Users with this particular use-case should investigate generating code in order to reproduce the upstream type
+    without the filtered out fields. For example, this can be done with [`projen`](http://npmjs.com/package/projen)
+    using [`jsii-struct-builder`](https://github.com/mrgrain/jsii-struct-builder).
+
+## Type Aliases
+
+TypeScript supports type aliasing using the `#!ts export type Name = ...` syntax. While this is not considered a
+compilation error by the `jsii` compiler, those types are implicitly de-sugared by the compiler for all language targets
+except for **TypeScript**.
+
+```ts hl_lines="1-2 5-6"
+// 👻 Only visible in TypeScript

+export interface Props {
+  // ⚠️ Effectively `readonly fooOrBar: Foo | Bar;` in non-TypeScript
+  readonly fooOrBar: FooOrBar;
+}
+```
+
+## Soft-Reserved Words
 
 In order to guarantee a consistent developer experience across all supported languages, `jsii` emits warnings whenever
 a declaration is named after any target language's *reserved words*, as those will need renaming in target languages:
