I agree.

I can envisage --with-tracing too, to build a Hat-enabled version
of a package, which involves not only extra compiler flags but extra
pre-processor and library dependencies too.

In general, do you think these flags should combine in a linear fashion
(one of each 'way') or cross-product (all possible permutations)?
