It might be nice to have an option on mount to determine what to do in order to please both points of view. I believe ext2 has this. As per mount(8):

     errors=continue / errors=remount-ro / errors=panic
             Define the behaviour when an error is  encountered.
             (Either ignore errors and just mark the file system
             erroneous and continue, or remount the file  system
             read-only,  or  panic  and  halt  the system.)  The
             default is set in the  filesystem  superblock,  and
             can be changed using tune2fs(8).

Not to diminish Set's original request, but to address this comment...

I guess your term "knee-jerk reaction" is subjective. I'd much rather
have a recoverable system than an unrecoverable one, which is exactly
what you'll have if the filesystem is put into an unstable state
(corruption) and isn't intelligent enough to protect itself from further
damage. It's also one of the reasons we won't use anything other than
XFS in a production environment.
