I understand that #nix fetchers "set a dangerous precedent" and this is why, say, #srht fetcher or other fetchers won't ever be accepted and #github shall have that socially privileged status...
But I also want to confess that the existence of fetchers make me so happy.
I really don't mind hosting or mirroring my stuff on #github because I don't have the time to pick _alll_ the battles.
