In general I'm absolutely with svdl's opinion.

For sure there are lot's of things that might be integrated into poser.
But in front of adding "features" it would be a real big, big benefit if SM would resolve all that dozen ... hundred flaws that are shipped since versions. That alone would be worth a version level 7.75, right ?

To have such a poser developer version is a really good idea.

With building in all that tools lot's of highly motivated people are designing over the time, I have my own opinion. Been in software development for about 20 year I have a clear look to that thingies.

For example have a look to windows. Since version W95 MS has started to add/build in a lot of gadgets normally everyone is needing. But have a look to that, e.g. zipping, image viewing, small text edits, dvd burning ...  All that's in now, but for a (semi-)professional it's useless cause only appetizers with less functionality ... and developed at low cost they are mostly dangerous for amateurs.
So as also in the beginning with W31 you need to get all that third party tools like winzip, irfan view, textpad, only to name some of them.  These are tools with full functionality for a specific purpose ... AND the main point, they are build by people being experts on that theme and being highly motivated, let's say some sort of enthusiasts.
The outcome is in each view lot's better than the results by big company people doing that. They are determined by personal development plans, cost reductions and such things ... but rarely to high quality in details. So it is in reality, don't hear the manager's telling other word's. Every of us is knowing this.

So in my view it's really essential to have a stable core application with well defined interfaces. Then specialized people can build additional tools and maintain them in perfection.

So things SM has to learn, for example to avoid such a crap like pushing real CR2-files as PP2 into the props section or pushing OBJ-files in the library paths instead of the geometrie path (all happen with P6). And that'S only simple things.

See, the organization of poser files might not be the best or logical or such ... but it is like a standard. And that means it have to be reliable for the people ... users like also developers.
There can be improvements, surely, but it have to be transparent and continuing developement ... not something a new software developer is doing cause not knowing what he's doing ...

A all in one application might be the target ... but it will never came and it will not work well ... and it will be over prized in every view ...
