Looks good to me, but would like to hear your thoughts on the reason for bringing those BCD keys in here, rather than flagging them in the BCD repo instead.

This feature originally made use of the web-features:paint tags from BCD, so the other option would have been to just add other tags in the BCD repo instead.

Maybe add a comment here saying something like:
"At the time of writing, additional parameters are not supported anywhere. When support is added, reflect on whether this should be split into a separate feature or not".

I feel like this might unlock specific developer use cases.

My understanding is that changes to a feature should be made in this repo. They eventually will get merged in with BCD, but I'd like to avoid making feature set changes in multiple repos.
