Yes, that would probably work. But it still make assumptions about how
the user is working on emacs. Probably I should just default the option
to nil and ask users to always set it explicitly.

Ha, yes, I got distracted. Unfortunately I haven't been able to
reproduce so far. I start Gnus with this in the init file:

(setq gnus-registry-max-entries 10)
(gnus-registry-initialize)
(defalias 'gnus-user-format-function-M 'gnus-registry-article-marks-to-chars)
(setq gnus-summary-line-format "%uM%U%R%z%I%(%[%4L: %-23,23f%]%) %s\n")

Mark some articles as Important or ToDo, stop and restart Gnus, and
everything is still present. I opened a bunch of other groups, so that
pruning (if that were the issue) would have dumped the entries with the
marks, but they are kept as expected.

Anything other way to narrow this down?
