I said that because you said this:

Anyway, SM63 was part of the childhood of a lot of us (including myself--I was around 9 or 10 when I started playing it), and that's why the level designing scene is still thriving on the forums. Even if the LDer in its final state isn't super optimal, people make do with it and enter some pretty amazing levels into our contests and the level portal. It definitely takes time and dedication to make a good level, but it can be done, and it can be a pretty fun process.
It's also possible an open-source project like the one Suyo started could get revived again, and the level designer could be revamped through that, so you could try gauging some interest in something like that (both on the forums and on chat) and see if any programmers around here are up for it.
