[cumulative reply :)]
While we could use a short-hand for HEAD also I don't think ~0 really is
a concern.
Regarding consistency:
We try to have reasonable defaults and try to dwim (which are different
things) even if that breaks consistency/systematics, because
useful/reasonable and "what I mean" depend on the context.
"^" resp. ".." and "..." are ambiguous and cannot be resolved easily
because for most commands they can mean two things resp. require two
arguments. (".." and "..." could maybe default do "@{u}..HEAD" etc.)
"~<n>" can only take a revision argument to its left, and also it needs
an argument to its left (as opposed to "^"). Therefore we can default it
unambiguously and without braking any current usage (that I know of).
Regarding rebase -i -<n>:
git-rebase (-i) does not have a log/rev-list like interface at all (just
like git-cherry does not), and introducing an argument which looks like
it did would just increase the user confusion, I'm afraid.
