I'll create a v10 branch so we can finally start working on this stuff now 🙂

[ota-meshi]

I believe the only remaining task is to upgrade the parser.
If not, please let me know.

[FloEdelmann]

There are two other open tasks:

• Drop support for typescript-eslint v5, v6
• Deprecate Vue 2 only rules #2675 (although that could happen later in a minor version)

[FloEdelmann]

After all the tasks are done, should we first release a beta version from the v10 branch?
And also, we should release a final minor v9.33.0 version that includes all fixes and features from the master branch before that.
