I am torn on that one.  Surely HEAD is often the branch that has our
current attention.  It may well be what we are exporting and we may
want to see the topology formed by other refs relative to it.

On the other hand, the current branch may not necessarily be what we
are exporting.  Historically a project has a single branch that is
the focus of most users' attention when they talk about the general
state of the project's progress, so it is understandable to expect
that the topology may want to be seen relative to that one central
line of development.

Yes, absolutely.  You either check "develop" out temporarily just to
take anonymized export to make "develop" discoverable in the output,
or you would have set core.primaryBranch to "develop" once sometime
in the past to tell Git that "develop" is that special one, not
"master", so you can take such an export from any branch.  As the
anonymized export is primarily/solely a debugging aid, convenience
would not be of much value, but the latter feels more convenient to
me.
