No commit description? It'd be useful to at least justify this by
mentioning that some platform will actually use this...

I would prefer to keep the syntax of the new formats consistent, so that
if we ever do add format-parsing code rather than table-based lookup,
all the existing formats will continue to work unchanged, without any
