Only if you have infante people to throw at a problem. The programmers all have different skills, and if the people you need to work on the zones rework are also the people you need to work on the shroud rework than you can't do both at the same time. So you have to schedule them for different points in time.
Right now, all their teams are working on backend stuff, and stuff for bio-rework. if they need their backend teams to work on the UI elements for the shroud rework and that is the rework they need the zones for--don't know making assumptions--the zones have to be done first.
Also, a large part of this scheduling is getting people to buy the game. Bio-rework and psionic re-work must be done soon, or people will get upset about those two not having the same number of interesting decisions as cybernetic and synth.
Also, they almost certainly don't want every update to include changes to the entire game. they want to keep those changes in as few updates as possible. if this was just pops. and the next one was just planet building you know they would push away people for changing things 'all the time.'
Then you have the other big problem. They only have so many programmers and they can only do so much work each day. And its not like any one programmer can do every job that needs to be done either. For all we know if they don't do all the reworks now, they simply won't be able to do the pop one for another year, because the people with those skills will have to be used somewhere else. for example, maybe the people reworking bio-ascension and related mechanics are the one's doing the pop rework. and so the people doing the zone rework are either doing that or nothing at all.
That makes sense to me, because if you are changing up pop-modding to allow for the clone version, then you probably want to make that less annoying for everyone. And if cloning means you have multiple species reproducing, then you probably want that pop group rework for everyone else at the same time.
The worst thing for a company to do is to have some of their people without a full days worth of work.
I guess my point here is that we don't know everything that goes into these decisions so shouldn't be second guessing them based on things we don't know about. especially the order of things. For all we know, they are in early design stages of latter reworks and can't start programing on them yet. And thus can't combine biogenesis with something else.
I'd be complaining about having to go into my management tab every time I built a new job and it 'free all jobs' or scroll around to find a new one. clunky and annoying, I think. There should be a solution out there somewhere. but that is not it.
