I do find myself forgetting which project is main and which is master so get confused a bit.
(Personally I find the use of 'master' in git fine - there has never been a 'slave' it was referring to; and 'master' is used in loads of other contexts in English; I've got a Masters degree, we have Post-masters, schools have masters and headmasters. I understand renaming it in master/slave systems though.)
