I refuse to care about this. A single dash is all I will ever use. I see no possible reason to use the other two.

It's not like you can reliably write these consistently by hand either without going over the top in length to make it extremely obvious.
Rather, seeing too short of a dash is like putting two clashing colors together or wearing two pieces of clothes that don’t match. It just looks instantly off.
It’s just not aesthetically pleasing for me.
