Sorry for the belayed reply here.

I was about to install this, when I noticed that this package is
actually maintained as an external package at:

    https://gitlab.com/phillord/persist

So I guess the easiest option is to continue running it externally,
unless you want to move its maintenance to elpa.git, in which case we
can arrange that.

If you want to maintain it externally, I guess Philip would either hand
over that repository to you, or you would have to create a new one.

Thoughts?
