Just because we went in a wrong direction then, is it good to go in the
same direction now?

I'm not saying it necessarily was a wrong direction, I just don't
consider that an argument.

You can consider my "log --cherry" being part of a long time plan to git
rid of "kinda-loggish but not log-like" command interfaces (in that case
git-cherry).

Introducing a shortcut ~n for HEAD~n does not introduce new
inconsistencies (it's a shortcut for a commit, for every command which
takes a commit) - and does not contradict introducing -n at all, btw.
But introducing -n means introducing a range like revision argument to a
command which does not grok ranges at all, so that is a much deeper
decision.
