You're right, but...
Actually it doesn't. Python 2 and 3 are not compatible. You can't use
> :python without knowing what version it is.
These days, many Python libraries support both of Python 2 and 3 in one
source.
For those, Python 2 and 3 are compatible at some level.
Jedi-vim uses alias command like this:
if has('python')
command! -nargs=1 Python python <args>
else
command! -nargs=1 Python python3 <args>
end
https://github.com/davidhalter/jedi-vim/blob/master/autoload/jedi.vim#L162
But, user defined commands can't be script/plugin local.
So having standard command like it is good idea.

If vim is build with -python +python3, those script just not work, too.
So, :python fallback to python3 doesn't break any scripts.
