I wonder why developer tools are not a priority for Apple for “pro” iPads. At this point, it uses the M2 chip so the limitations on running IDEs, compilers and other tools just seem arbitrarily imposed.
The main problem, I think, is most development tools require a relatively low-level of operating system access that Apple has not figured out a way to do given what they want iOS/iPadOS to "be".
My suspicion is they'll eventually find a way to do containers in a manner that's relatively "safe", and they'll lean on Cloud-based build tools that move the hard work off device.
