Problem is that xassert quality is rather different: most are basic
structural safety checks which would seem to exchange difficult to
find crashes and inconsistencies for easier debuggable ones.  Then
there are quite a few that try checking for visual consistency (like
cursor movements making forward progress).  They exchange a possible
nuisance for a catastrophe for the average user.  And they don't help
in debugging actually since you don't get to see the problem on the
screen...

The visual asserts are probably also mostly the expensive ones since
they sometimes have to walk through data structures to get their
condition.
