Yes, they are part of the team ... and each has taken on various levels of their final roles - but as you will note in my response to you - they are not up to full capacity yet. See:
#5,991 where Breadman talks about how much each has done of what, etc and that while GhostMoth wrote most of v0.5 - Breadman wrote the majority for the coming v0.5.5. Also, that Breadman is "still handling all of the Production duties for .05.5."
if you are a member of their subscribestar or in their discord, in their own communication channels - the team makes no mystery of what's going on. They also put out a visual chart of progress each week. And they do share and answer questions here, as they have time - but communicating in their own sites take priority over communicating on F95. See:
#4,848
search "full save" in the thread - voila! Or load the preloaded save in slot 50 and take a couple hours to play through v0.5.
