Why 'sadly', i wasn't complaining, just reporting my findings, and
looking for other's opinion.

Agree, convenience tends to bring un-repeatable 'magic'. Strictness
brings repeatability, but is usually verbose/noisy.

Something else I've just discovered about qmake, is that you can
'forget' which Qt module you depend on. Qmake seems to scan your
source file and add missing Qt dependencies automagically!

How can you trust a tool that do stuff "on your back"...
