That's developing logistics for pails in order to deal with an
unfinished roof because nobody remembers where the trapdoor to the attic
was.  The number of bugs is not the problem.  The problem is that the
skills needed to deal with the bugs and other problems are not in a
sensible relation to the complexity of the bugs.

A _sensible_ investment of time would be to move a considerable number
of engravers to Scheme.  And keep them _there_ rather than just doing it
as an example.  Presto, we get a bunch of code (_iff_ the style of
Scheme is not wallowing inscrutably in macros and idiosyncrasies like
some of the C++ code) that can be maintained with more confidence than
"poke with a stick and see what happens".

Then the roof at least leaks in accessible places.
