What stops the time-based trigger from not being active when the shutdown
would fsck, but becoming active in the next boot?

A simple call to fsck after umounting filesystems would avoid triggering the
max-mounts-since-last-fsck trigger on boot for everything but the root
filesystem (which we can't umount), but fixing the two remaining boundary
conditions ain't that easy (rootfs, and time-based fsck triggers).

With some testing, maybe we can fsck the root on shutdown *when* we succeed
at remounting it read-only (but we have to make sure the behaviour, should
fsck find any errors, will be sane.  And that does mean not changing a power
off into a reboot, etc).  For time-based triggers, the only fix I can think
of is to disable them in the filesystem itself.

Note that I am not against a partial fix at all, send the patches in :-)
But it would be nice if we would change the installer and mkfs defaults to
avoid enabling any time-based triggers by default.
