So what? You prefer smaller compiler, but worser generated code and
less functionality (both language and library)?

Any product need maintain. Why your suggested compiler will be better
in this? The more so - OW _does_ (more or less) maintained, who will
maintain your compiler? Especially, C and C++ are very ugly languages and
there are much of dark places in their standards?

Because writing good _and_ bugless optimizer is really not easy task.

Ok, if you think, new compiler should be written - go ahead. But not
expect, that there will be much other contributors/maintainers for your
program until it reaches some noticeably useful stage (at least, I not ready
to participate in this project on earlier stages). And this is years of
working to achieve this stage.

GPL does not requires to get any permissions to reuse GPLed code (while
your derivative work is also GPLed).

For me, trouble is not that there is not enough free(dom) (and open
sourced) assemblers, trouble that there are not much _good_ assemblers with
much support for high level features (optimize for instructions, support of
interfacing with HLL, HLL contructs like PROC, IF/ELSE, etc).
