Yes.  It all boils down to "what is the most common thing people
would want" and "which one of these operation modes deserve the
short-hand".

Most often, the first one that gets invented ends up squatting on
the short-and-sweet "by default without parameter, we do this" slot,
and we have to let it squat forever due to backward compatibility.

I think "git branch" that shows all 300 branches is a good example
of that--if we didn't have command line prompt support, I am
reasonably sure that "git branch --current-branch" would have been
added by popular request long time ago, and that would be a more
common thing people would want than "git branch -l".  I would not be
surprised if in an alternative universe in which both "list" and
"tell me current" were available back when the "no option default"
had not been defined yet, we gave the shortest-and-sweetest to "git
branch ---current-branch".
