And when this is stamped out code from a macro or template instantiation, should it also not be removed? What a silly optimization to leave on the cutting room floor. Compilers could probably better track this stuff to know the difference between macros and template code, but it doesn't seem to be high on the priority list right now.

It's not high on the priority list because people just couldn't agree on what things should be retained and which shouldn't be retained.

Without clear, consistent rules there are nothing to discuss. No matter what the compiler does or doesn't do there would always be someone who would claim it's wrong behavior.
