In my eyes, doing this always seemed wrong, I wouldn't mind if it
returned an error.

I actually like the idea of adding a DefaultInstace= option to the
install section. Instead of fiddling with aliases manually, it could
look like this:

[Install]
WantedBy=getty.target
DefaultInstance=tty1

Instead of going to [Install], this could even go to [Unit] and affect
start/stop, not just enable.

Manually writing an alias here seems redundant - you shouldn't have to
write an alias when what you do is pretty much standard.
