I see no particular reason why we shouldn’t add a Pivot tool to allow users to interactively move, rotate or scale the pivot. Or it could be added as an option inside the current transform tools (this may be nicer)
AFAIK there’s no particular philosophical apposition to adding this - it’s a fairly basic feature that Blender, for whatever reason, has always lacked. Blender would benefit massively if it had a full-time developer working on these tool-related topics.
The addons to do this are interesting, but are essentially hacks. A proper implementation of this would have to be done differently, in a more integrated way.
