It's not "expected", but in order to know whether to resubscribe them,
you need to know why they were unsubscribed.

Here are some possibilities. Presumably the actual unsubscribes were of
bouncing members by cron/disabled. Possibly cron/disabled was not
being run before and the server/Mailman upgrade installed a new
crontab for Mailman.

Prior to Mailman 2.1.10, if bounce_score_threshold for a list was
reduced, members with stale bounce info with scores >= the new
threshold would be disabled and/or unsubscribed. This wouldn't explain
your situation unless you happened to reduce some
bounce_score_threshold settings.
