Presumably the overhead for entry points is only relevant for scanning
installed distributions looking for entry points? In my JSON metadata format,
I currently have the entry points data as an "exports" sub-dictionary in the
main meta-dictionary, but this is written to a separate file during
installation so that only that small part of the metadata needs to be checked
when e.g. iterating over entry points in a group.
