Angular input on Interop 2023

[foolip]

@robnyman has talked to the Angular team to get input on the Interop 2023 proposals. The source is
the Angular input on Interop 2023 spreadsheet, inlined here for convenience:

Feature	Rank	Affected area	Why it matters to Angular
CSS Scoping	P0	Framework	Angular (along with Vue and Svelte) emulates CSS scoping, keeping component styles from leaking out, but still allowing global styles to appy. Browser support for this behavior would simplify the implementations of all of these frameworks.
Produce consistent accessibility trees	P1	Components	We've run into issues over the years with different behaviors between browsers. While it's true that most problems stem from screen reader differences, having consistent browser behavior would reduce one source of variance.
Navigation API	P1	Framework	Stands to simplify Angular's router implementation if it were consistently supported in all browsers
Import Maps	P1	Framework	Supports deploying code as ES modules directly, without a bundling step
Sanitizer API?	P2	Framework	This would reduce the code necessary for Angular to sanitize HTML content
Container queries	P2	Components	Game-changing power feature for CSS authors, not much needs to be said
:has	P2	Components	Game-changing power feature for CSS authors, not much needs to be said
Temporal	P2	Framework & components	Might simplify some datetime handing in a few framework APIs, but would make it possible to build a high quality datepickers and time pickers on the UI components side without complicated adapters for 3rd party libraries (Moment, Luxon, date-fns, Date.js, goog.date)
Pointer and mouse events	P2	Components	Inconsistent behavior here is a common source of debugging woes for UI component development
inert	P3	Components	We have quite a bit of code to do focus trapping for dialogs today; inert could potentially simplify this
:dir	P3	Components	More correct over current approach of [dir="rtl"] and would eliminate the need for custom code to track the direction in JS
:blank	P3	Components	Convenient, especially for Material-style floating label inputs (in combination with :has)
:empty	P3	Components	Convenient, especially for Material-style floating label inputs (in combination with :has)
Clipboard API	P4	Components	Nice to have, but current solution is mostly fine
Focus outline	P4	Components	Could simplify focus rings (go/gm3-focus-rings in Wiz, strong focus in Angular), but would need to also include outline-radius
Range syntax for media and container queries	P4	Components	Convenient, nice to have

I should just mention that @jelbourn in the Angular team and @kara at Google have also helped tremendously with gathering these needs.

Just a quick suggestion - if you gather input from Angular team for interop proposals it would be great to get input from the React and Vue team too.

You can get in touch with @gaearon Dan for React for example. He is even tweeting about borked things across different browser sometimes.

Could you copy these into each of the respective issues? Easier to know what was said about each one, rather than having to reference this.

Agreed! We asked those two teams for input last week (as well as a few others) and are waiting to hear back.

Hi @kara, is there any response from React/Vue/Svelte, etc.. teams?

@kbrilla note that we're in the final stages of finishing up Interop 2023 for launch, so additional feedback at this point won't change Interop 2023.

That being said, it could always inform what we do in the future.

Interop 2023 launched yesterday, so closing this.
