+1 for putting it last.

It defaults to "." as the target in that case. I never liked that it
was allowed to be optional as I think it makes things much more
confusing than the two characters saved.

Mostly agree. With symbolic links the symlink contains a string. The
string could be pretty much anything. By convention it contains the
path to another file. (Or to another special file. Everything is a
file.) But it is also used to contain a small bit of information in
other cases. Such as for lockfiles and other uses. Therefore source
isn't quite right. But maybe it is good enough. Because CONTENTS
seems less good even if perhaps more accurate.

mv calls it SOURCE and DEST. cp calls it SOURCE and DEST. Perhaps ln
should also call it SOURCE and DEST too for consistency?
cp [OPTION]... [-T] SOURCE DEST
mv [OPTION]... [-T] SOURCE DEST
ln [OPTION]... [-T] SOURCE DEST
I like the consistency of that.
Although I don't like that -T is not apparently an OPTION. It's not?
Why not? Shouldn't that synopsis form simply be these?
cp [OPTION]... SOURCE DEST
mv [OPTION]... SOURCE DEST
ln [OPTION]... SOURCE DEST
