There’s a semantic difference between “supporting mods” and “provide support for modded installations”. The former is fairly common and is what steam workshop is about and is what you are talking about.
The latter is basically unheard of (for what I hope are obvious reasons).
The OP is a bit ambiguous about which of the two or is.

Steam workshop isn’t mod support. It’s a place to get mods. Mods work without developer support, always have, always will.
