Hi! I noticed that all of the eslint-disable directives and TODOs for converting interfaces to type aliases have been removed in this PR.

The shared libraries team relies on those comments to mark interface instances that were pre-existing at the time we enabled @typescript-eslint/consistent-type-definitions, and to keep track of remaining interfaces that need to be converted.

We'd appreciate it if you could restore them in this PR before you mark it as ready for review.

Additionally, any new types being added should be in the form of type aliases, not interfaces.

Please refer to the following for previous discussions on this matter:

• Forbid TypeScript interfaces eslint-config#216
• Re-enable @typescript-eslint/consistent-type-definitions #1933

Edit: This PR seems to supersede #3900, but if not, please apply the same to that and any previous PRs as well.

Edit2: Is this PR maybe not intended to be merged into core?
