... as if such unfree backend would have any credibility while trying to compete with
the free backend of the GNU project ... Even Visual Studio experiences increasing
difficulty holding its beer against a free GCC.
Next, this concern seriously underestimates the hard work involved in creating and
maintaining the various assembler generators that target all the platforms that GCC
can currently handle, not to mention the linker and its multiple executable formats.
Finally, the full AST is useful to free software developers in the first place. It is
them you would be impeding the most.
