Files that were dynamically created and that I could delete at any time hardly seem like an authoritative place to check what modules are installed on my system.  It’s far more likely that they will be out of date later on when I update or remove a system library.

It still looks like needless duplicate info to me.  Besides, installing Qt in my home dir is not at all a standard thing to do (it’s only that the Qt installer does it).  The standard thing is to use distro-provided packages.  And if it becomes necessary for those packages to include qbs-related metainfo, they will end up under /usr somewhere.  But maybe it’s better that qbs learns how to use pkg-config, unless there’s a good reason not to?

Of course not only qbs.  ;-)  Browser profiles make a bigger mess for example.

yeah, sigh (but dropbox is an easy thing to avoid)
