Why is not spending resources to develop infrequently-used features that aren't revenue streams "stifling"? Granted, I too would love to have nice UIs for those out of the box, but > 99.9% of Mac users don't care, and 3rd-party developers can pick up the slack and maybe make some money filling the gap.
that's the short-term, MBA-style mindset to which I'm referring. Much of the popularity of MacOS came from the open source community filling that gap despite lacking support. So there is clearly demand that the PMs were not tapping into.
It would be fine if Apple was providing the APIs, docs and support to stimulate 3rd party tools. Hyperkit sat undocumented for 15+ years until a proper hypervisor platform was built on top of it. This sandboxing framework is another example.
