Sacrificing -O0 optimization is just a desperation move, since

I would not look at it that way. We have, will generate and solicit
plenty of ideas. It would be nice to have in place a design that
explains to ourselves where to fit in the various pieces. One way to
think about it is as a marker for code that should be rethought or
improved.
For example, slot combining should be so trivial and run so fast that
it would be impossible to measure the effects of it. By marking it as
slow, we give ourselves the opportunity to improve the code. :-)
