A month ?
"My" exporter (Blendigo) got updated the last time in January and received 2 few minor fixes since then. Well, 4 really but I did the last two myself
I suggest that the devs are quite focused on v4. Afaik this Cindigo Update wasn't done by fused only during lunch break, but took quite a while also with some private free time invested...
I'm very positive that once v4 will be on the horizon also all exporters will need updates and some polishing!
If the community could manage to maintain some proper bug/feature list, there will be the best chance that devs will work trough it
I report Bugs and Feature requests for cindigo on a weakly basis with atm over 90 tickets only for the C4D exporter (many fixed meanwhile).
