Office 365 / Office 2021 not present in ReplaceOfficeVersionInVBAProject

[strictlymike]

I noted that 32-bit Office 365 saves macro documents with a VBA Project version of B2 00, which I didn't expect because I thought it to be associated with 2016x64 and 2019x64:

Didier Stevens wrote about this phenomenon and didn't seem to reach a conclusion on why this is:

I would have simply guessed that the same p-code compiler was carried forward from 2019, but if that were true, I would have expected the version to be AF 00 like the other recent 32-bit versions instead of the version number that has been associated with 64-bit.

By way of letting you know that O365/Office 2021 is absent from the list of valid Office versions in your switch construct, I thought I would ask if you've encountered this too and learned anything about it?
