It does take some work to get these things working good on consoles. Optimization issues with textures, scripts, etc. A lot of the big name modders also have a number of mods they have released so they have to spend the time on all of their mods making sure nothing breaks for a console release. Most of them are/were actually working on it but a one-two combination of having people steal their mods so impatient people can have it now combined with, they claim, getting spammed with tons of "where are your mods for the console" has worn them down. A lot of it comes down to a bit of a culture shock. The PC modding culture it pretty entrenched in their ways which have been set for, in some cases, 15 years or more. To have this massive rush of the console crowd just walking all over the way things have been done in the past is just rubbing them the wrong way and Bethesda is doing neither side any favors in mediating so far with their ham-fisted attempts at forcing themselves into the middle of it all.
