That is just one very simple part, connecting the mouse. Literally everything else sucks on iOS. File management, hidden menus, running multiple apps, system management... and the list goes on. Need to convert a STEP file to something else on the iPad? Download 15 apps to see which one works, then try to find the converted file in the abomination of a file system? iOS is hot garbage.
What if you've learned how to work around many of iPadOS's limitations and still think those limitations are bad?
Downloading 15 different paid or free-with-in-app-purchases or free-with-ads apps to see which one actually does what it's supposed to do is one of those workarounds. I've learned how to do it and done it a bunch of times and I don't really like it. I much prefer the macOS/Windows/Linux workflow where there's typically some established, community run and trustworthy FOSS software to do whatever conversion you need.
