As I cant provide numbers anymore it is also just anecdotal evidence.

Both, in a way: The huge number of includes is the root problem, but not
trivial to fix. The number of -I-switches to the compiler being performance
relevant is a symtomn of that and reducing those might improve build time, but
it is not fixing the root problem.

Fixing the root problem might involve a git hook that gives you an angry stare
for 30 seconds everytime you add more lines to a >1.5KLOC hxx than you remove
from it.

Indeed.
