I can think of some:

 - wanting to be sure that setting hardening flags on these packages
   through the dpkg-buildflags mechanism will actually work;

 - guaging whether the mechanism has reached the level of adoption
   to warrant inclusion in policy;

 - wanting to be able to work around new toolchain changes (think:
   -fno-strict-aliasing a couple of years ago);

 - wanting different flags on some machines (like Ubuntu's -O3 on ppc,
   though I don't understand why);

 - generally speaking, wanting DEB_BUILD_OPTIONS=noopt,
   DEB_CFLAGS_APPEND, etc to work widely.  Checking is the obvious way
   to make sure it actually happens.

Thanks.
