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 our wants
And you get battle-tested software and a huge collection of existing plugins, operational modes, export formats, all that. Fully bespoke software for everything you want is a way toward losing interoperability between people and platforms.
But building up as opposed to building down is freeing in that I can also pull in ideas from Houdini and mix them in. Not to mention BECAUSE Blender is OSS, i can also use it as reference for implementations of particular things should I need that too.
IMO, this kind of full customization is going to become far more commonplace.
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.
