Hello Alan !
Yes indeed, one of a very great thing with blender fundation is that they are very communicative and transparent about their roadmap, and their projects in general. This in fact push the community to get very supportive and also more patient. As we can clearly see they doing their best and take good decisions. Feature are lacking but we can follow them, knowing that it's just lost in a giant todo list and eventually it will get there.
Being able to access weekly reports on BF activity is very great too.
In fact being comunicative for blender is a necessity, with ~100 peoples contributing to the code it's a true need to keep everybody in sync and also motivated.
I think Natron actually took too much time for dev's to invest time in community management and comunicate about their plans. The other thing is that the roadmap evolves too much . Some features that was planned long ago are still not there and other ones appears (like tools related to optical flow, shadertoy) .
That said Alexandre sometimes make some reports on current dev when asked on the forum . Natron 3.0 is a big step in the core tool (rendering engine, .ntp format ect...) If I understand correctly it's more about laying out a strong bases than getting lots of new features (even if these changes will also allow more possibilities).
I guess we need to give Natron a bit of time to let things like this organised. Indeed Alex and Fred are already doing their best and work a lot on Natron. Once it get's used and properly funded comunication will improve too.
Blender was also open sourced with a kind of kickstarter (to buy the code source from NaN) (they already build a strong comunity at that time) Then communicate with these people who paid to free blender was also part of the game from the start.
I think for now with Natron it's up to the comunity to get organised and suportive too. That's the least we can do.
One could for instance send a mail every 2/3 week to Alexandre and ask for a brief summary of what as been done and make a blog post about that. I'm sure it will be benefic to many and may chill the fears that people can have without knowing what's going on...
