If we know which regexps cause problems, shouldn't we instead fix
those regexps, or change how we use them?
For debugging purposes, you can set the value in the debugger after
starting Emacs, or with a breakpoint just before calling the
problematic code.
As you have seen from the history of this value, it's problematic to
calculate, and the meaning of the value is not obvious. So exposing
this to Lisp would be a rope that's too long to give our users and
programmers.
