The problem here is that it didn't find the Qt update, for some reason. 
Everything else you report below is inconsequential: if the maintenance tool 
had updated Qt, none of the problems would apply.

Also note the problem might not be in the tool, but in the server-side 
metadata.

That's a known issue that is declared "design decision". The Qt installers are 
inherited from old Nokia-era "Qt SDK". The minimum thing you need for the SDK 
is the IDE, as you can pick and choose your combination of Qt targets. 
Therefore, you cannot uncheck Creator.

That's a good question.
