AFAIU, this will show nothing when the matching parenthesis is not
found?  If so, why is that a good idea?

In general, I don't understand why this rare situation should draw so
much attention.  Does this happen to you frequently?  If so, does it
happen with many files?  You could solve this either by changing the
value as a file-local variable or globally by customizing the limit in
your init files.  What I don't understand is why should we make
significant changes that will affect everyone, when the problem is
rare and affects only you or a small number of users?  User options
exist because no single value can ever be good for everyone or every
situation, so the right solution for such cases is to customize the
option.

Or what am I missing?
