There's plenty of reasons to not use that platform:
I don't like its interface. I don't like its organization. I don't like their Vortex client and I don't like having to keep up with mods manually to have them up to date, either.
Steam Workshop support would spare me from every single one of these things, so I'll gladly use it given the option.
All of this. Steam Workshop is vastly superior to vortex
Except Vortex automatically tells you if mods are outdated, gives you version control over mods, gives you load order control, and lets you manually check out and if necessarily modify each mod.
But yeah, let's tie modding to a client that doesn't support the entire player base and offers a dramatically worse service.
+1, seriously.
Tuco when was the last time you used Vortex? It auto updates mods, it tells you if there is a conflict, it makes recommendations on load order and warns you about possible conflicts. It makes it super easy to "suspend" a single mod in the sequence if it is not working right and also lets you transmit mod "kits" to other users who you may want to play with so you are all using the same mods.
I mean, nothing against Steam workshop, I use that as well because it's right there but it's just not going to be active day one, and it doesn't have the bells and whistles of vortex. If you are fine waiting a month or two for it to be set up then fine.
If however you want Variant Human on day one - Nexus mods is your boi.
