Arbitrary Island locations

[ceigey]

Hi all,
I noticed in "The road to Fresh 2.0" (#2363), there was a hypothetical app.addIsland(...) method proposed briefly which I found interesting.

Currently it seems you can manually declare islands with the Vite config using the islandSpecifiers array, but it doesn't look like there's anywhere to declare a glob of "island" directories, which might be useful for more advanced use cases e.g. adopting "organised-by-features-not-concern" directory structure.

E.g. let's say I have:

/features
  /users
    /components <- fullstack
    /handlers <- server
    /islands <- client
    /pages <- fullstack
    /services <- server

(let's assume I'm not using file based routing at this stage and I'm wiring up routes manually)

It'd be cool to be able to have any components in /features/users/islands work like any normal island.

Maybe this conceptually clashes too much with the framework though; I've just found this sort of structure nice in a FastAPI (Python) project and now I'm trying to imagine my ideal counterpart in the JavaScript world, where we have the benefit of using the same language on the fronted and backend, which is especially convenient for SSR purposes...
