You’re right: Record the top-level names of a wheel in `METADATA`? (and no, I wasn’t involved, because people covered my position just fine so I didn’t have to chip in 
)
Looks like it’s just waiting on a PEP to decide where to put the list of top-level names in metadata, but the general consensus was that RECORD is fine for 99.9% of cases and the 0.1% should feel a little bit bad about whatever shenanigans they’re up to.
