Can you credit @Davier as a co-author in the PR description to make sure this gets into the release notes properly? :)

Just like in the previous PR, I'm very happy that this exists and content with the underlying code.

Only thing I think this needs is basic docs on ReflectResource.

I won't block on this, but if you want to put more work into this PR:

  1. Docs on ReflectResource methods.
  2. Consider enabling reflection for more resource types.

I like it! Looks very useful. I have some docstring suggestions for the functions; feel free to modify them, especially if the doclinks don't work. They should, but sometimes doclinks are wonky.

Thanks for the tips. Updated the documentation. Please, take a look.

Some thoughts for the future PRs:

  • Maybe it worth to rename add_component into insert_component?
  • Maybe not panic in apply_resource / apply_component? Or introduce another function apply_or_insert?

Just one little nitpick, but otherwise LGTM!

Maybe it worth to rename add_component into insert_component?

Can this be included here for consistency with the added insert_resource or out of scope?

No strong feelings. Feel free to include it if you'd like; reflection is getting basically a full rewrite in this release anyways.

If you do, note it in the migration guide.
