Thinking about it a bit more, I think my wording was a bit too
strong and needs clarifying explanations.

In a case like this, a fix of a "misfeature" for somebody is a
regression for somebody else.  Because there is no single right
default that is appropriate for everybody.

At least having _one_ default (and picking arbitrarily the
historical default as that one default) is better than no
default at all.  The former will not inconvenience anybody by
forcing what has been necessary from before.  The latter will
hurt the lucky ones whose preferred way happened to be the
historical default.

Keeping the status quo, however, will inconvinience unfortunate
people whose preferred way was not the historical default.
That's where we start to tackle the problem, by introducing the
configuration variable.

If we can come up with a way to tell projects that use the
workflow better served with --current, perhaps when a remote is
added to the repository (either the initial clone or "git remote
add") and/or when a new branch is created.  If we automatically
set up the configuration "push.defaultRefs = current" in such a
case, I suspect that we do not have to have the built-in default
(at least, the value of the built-in default would not matter
much).
