Why global store?

[dkotik]

I could not find a way to narrow $post submission to specific fields - the library appears to drag the store from the entire page. It is very jarring to me: makes it difficult to debug, predict unusual interactions, worries me with prototype polutions, and things breaking in the future if multiple forms or dynamic sections are present on the page. Why not scope data-store specifically to the children of the element which has it?

If that is not possible, is there a way to specify the elements which go with specific post body?

This is by design. Store values are nestable, which is the easiest way to “scope” things when necessary.

For example:

<div data-store="{form1: {field1, field2}}"></div>

How can I $post only the form1 key, not the entire store tree?

You cannot choose what to post, but you can nest to your heart’s content.
