Again, why? If someone wants to create a scamcoin, they can. If
someone wants to burn money on a scamcoin, equally, they can. I'm not
sure how this is any different. If someone manages to garner realistic
support for a hard-fork, I don't see the benefit in forcing them to
use forked software.. that only leaves Core in the middle because it's
forced to choose a side (not choosing is unfortunately a side as
well). It doesn't remove the reality of the split.

Well of course. It would be a terrible idea. People would try it and
fail, and lose money. But for those crying foul at Core for being the
consensus/policy gatekeeper, it seems to me that user-selectable
params is the only logical solution.
