I've never worked with Avisynth before, but shouldn't that program have all the functionality of Premiere?

A few Google searches pulled up this:

So if I understand it correctly, you could use Premiere as the editing program, and output in Avisynth. I think?

Yes, but that still doesn't give you the ability to share your color correction here as a simple text file that we all can use and modify to our liking.

This is one of the biggest strengths of Avisynth, as it's more-or-less a programming language for video work.
