Linter does not complain about API split up into multiple files

[caugner]

What type of issue is this?

Linter issue

What is the issue?

Example: #29040

• webassembly/api.json had webassembly.api.Memory.toFixedLengthBuffer()
• webassembly/api/Memory.json has webassembly.api.Memory with sub-features

What behavior were you expecting?

My expectation is that if webassembly.api.Memory has its own file, then all sub-features must be in there (or in webassembly/api/Memory/*.json for that matter).

What version(s) of BCD is the issue present in?

• The current BCD release
• The current version of the main branch

Do you have anything more you want to share?
