PEP 665, take 2 -- A file format to list Python dependencies for reproducibility of an application

The locker should not produce this value. It can still produce multiple lock files with different tag values that combine to cover all platforms, but personally I am skeptical anyone would ever bother to specify platform requirements in such a fine-grained fashion. If this use case really becomes somewhat popular, we can easily amend the spec to also allow an array.

I misread the description of tag and naively assumed the locker would combine all the wheel tags from the package array into tag. Could you explain how this field might be used?
