Hey there!
Even Better TOML is a relatively recent extension that doesn't have a high level of usage yet. How necessary do you think it is?
If we could leave it out for now, we're happy to add the other two extensions to the definition.

Hello

How necessary do you think it is?

At the time I made the PR, Even better TOML was the only TOML extension that had autocomplete for Cargo.toml files. Meaning that it was the only extension that had schema support. Other extensions didn't seem to do much other that syntax highlight (I could be wrong about the last part)

Giving this a bump, switching from RLS to rust-analyzer would make using the official devcontainer a smoother experience.

hi @midnightexigent , I guess there may need a git rebase, let's do this? I believe this is the final step that the PR get merge.
