I think the value of adapting full tools to your own workflow far outweighs the maintenance costs nowadays. The tool above for instance took my agent a couple hours and it was good to go. It wasn’t a small slice by any means either: it supports edit/obj mode, extrude, loop cuts, modifiers like subdiv, save/load, undo/redo, bones, auto rig, posing, and more.
Mind you, this is a slice of an open source tool which was still outside of what I wanted from it. Cost wasn’t even part of the equation here.
I could start from scratch obviously - but seems a shame.

Since Blender is OSS, you could probably use one of the existing VR views for Blender and write a bunch of in-app Python scripts to do what you want, if you wanted to also be able to output to Blender files and work within Blender already.
This looks like a pretty well-trodden area in Blender.
Adding scripts into an existing product does not serve this.
I think we are entering into a new era where we don’t need to accept fully featured software with all of its decisions should they not fit ours.
