Please stop, ignoring my feedback, not detailing what problem or
problems you are actually trying to be solved, and threatening to merge
code into files that I maintain that has the express purpose of breaking
my users.
You just artificially constrained the problems, so that no other
solution is acceptable. On that basis alone I am object to this whole
approach to steam roll over me and my code.
