Is it allowed to upload resource packs?

I was just wondering if people are allowed to publish resource packs (using the modification publishing system) to the MCreator website, if the resource pack was made using MCreator. I looked at the modification publishing guidelines, but resource packs aren't mentioned on it. Specifically, I would like to know if it is allowed to publish resource packs through the modification publishing system, what category to put resource packs under, and if some resource pack types are more/less desirable than others?
