I strongly agre with this. In the case of GNAT, our standard is to bootstrap
with the option to make all warnings into fatal errors, and once you start
this, it is relatively painless to stay there, but getting there can be
an effort (indeed we are just about through quite a big effort of making
sure that the new GNAT sources do not generate warnings with -Wall, and
finishing this off, which is a day away from being complete, was the last
remaining job to be done before we put the sources at gnu.org.
