There are a few reasons I ask this, the most notable being that;

1. I'm on Linux, I cannot use VCC at all to begin with.
2. I'd rather avoid having to deal with VRCFury itself and be able to manually set up stuff myself(I can do so just fine without needing automated tools anyways for the most part.)
3. I'd optimally like to still be able to use SPS even if it has to be a standard Unity package for vrc avis I myself decide to upload to my own account.

Ultimately it'd be nice to have it so that I don't have to go through the trouble of manually converting avis over to DPS/TPS(the latter of which confuses me to some extent as to how it's supposed to even work remotely.) painfully.
