Yes, but users are forgetting to enable them.  They will work in
a new repository having that feature, move to an older one and not
have it, but expect it to be there.

As I recall the primary objection to enabling them by default
when I first introduced them was that core.logAllRefUpdates=true
meant that refs/tags/<name> were also being logged.  This was not a
great idea as tags generally did not change once they were created.
You fixed that and now it just makes sense to enable it for branch
heads all of the time.

I almost did that in my patch - but decided against it for the
reason I just noted above.

Does anyone on the mailing list really have an objection to having
reflogs on by default?

About the only trouble that can cause is a failed push when
git-receive-pack needs to generate the reflog entry but cannot
get the user's committer data because their gecos information
doesn't exist.
