If I understand your question: sequence names must start with a
letter. Fortunately. That's documented in mh-sequence(5) and
enforced by the code:
$ mark -seq 42 last
mark: illegal sequence name: 42
$ echo $?

Okay, fine, clearly that's possible ... but the code is not
structured to take advantage of that.
Agreed. Also, the space-time tradeoffs we'd make now would be
different than those that were made 30+ years ago, and would
no doubt significantly affect that code structure.
pick now calls folder_read() twice: could we remove one of
them, at least sometimes? The first read is without
locking, which is good. But I don't know if we can reliably
bypass the second one for cases where the sequences file was
already up to date. And I don't know if it'd be worth the
complexity to try.
