Yes, I considered this too. But to get it right it's a lot of
work, which seems to be silly for such a "small" problem. And
then, if I don't do it right, using the alias approach above is
much simpler and not much worse. :-/
Just to better understand the situation, is there any technical
reason to limit the scope of aliases to the first word of the
command line? After all, zsh already has to look everywhere for
global aliases.
Btw., there's no simple way to do regexp search and replace on
command lines like
s/^(git\w.*\wrebase\w)(.*)/\1 --keep-empty\2/
or is there? (\w is an ad-hoc expression for a token boundary)

According to the man page, you can only define new aliases, not
overwrite subcommands.
$ man git-config
...
To avoid confusion and troubles with script usage, aliases that
hide existing git commands are ignored.
