No, the bar is 'basic functions work reliably', that's not too high.
I'm not saying they're 'ignoring linux voices', I'm saying that they are unskilled at being linux devs, and thus what they deliver is less, actual linux functionality comes off as an afterthought.
In fairness, they do seem to be learning as they go, but they do have a ways to go.
Its really, really obvious that the people involved in the dev team have basically all their modding / mod tool development history in Windows, never bothered with linux support before, let someone else figure that out for them.
Ironically, Vortex run through proton or wine environment that includes Vortex's windows requirements works better than NM, so... yeah, they're not that good yet at this whole linux thing.
