That can happen with SELinux when the application does something
unanticipated by the policy writers.  It can also happen just the same
with ReadOnly Directories, for just the same reason, can't it?

I suppose there may a difference in how often that happens - "/usr is
read only" is a fairly well-targeted heuristics, OTOH "/usr is read
only" also leaves a large part of the system completely unprotected.
