That's how it used to be, and I found the mandatory two-level directory 
structure rather annoying.

Exactly ;)

Note that this does not enable you to have a "catch-all" qbs build 
directory. For instance, I work on both released versions of QtCreator 
(which still gets bugfix releases) and on the current master. The 
project name is the same, so I cannot use the same top-level build 
directory, since the profile names would not be unique. So I already 
have something like "builds/creator-2.6" and "builds/creator-master", 
and the actual profile-specific build directories within. Now with your 
proposal, it would say "builds/creator-2.6/qbs-build", plus e.g. 
"Qt5-debug". The additional namespace doesn't give me anything there, 
except higher blood pressure due to more (mis)typing.

Against non-qbs stuff, you mean? That can easily be fixed by adding some 
prefix.
