I seem to notice that there is no request to remove emulation of the systems, but only the links to the ROMs
Correct, and such a request for the emulators won't be possible at all: it's definitely not forbidden to write an emulator for whatever program/system you want, as long as you don't use any original code.
And so removing the Vancouver emulation from the Mess-SVN a few days ago is absolutely incomprehensible for me!
While they're not legally obligated to do so, MAME has removed drivers at the request of the rights holders before.
