Curious how words can appear ambiguous... ;) In my understanding, the size has
nothing to do by itself with signedness. And from the previous discussions
seemed obvious (to me) that, as regards integer types, people want warnings
only when the size of source and target are different (smaller for target).
Floating points are not at issue, also rather obvious to me, should remain
untouched in -Wconversion.

Confirmed that so far I haven't found any larger signed -> small unsigned
conversion, personally, I would probably explicitely cast anyway, in that case.
