I think it is fairly sane to just insist that SI units take precedence,
especially given that we support multi-letter unit names (e.g. pt, px,
mm, cm), so min will do fine for minutes.
I find this attention to physical units a bit improper. Sure, some
drawing applications or text editors should be enabled to draw UI
following specific physical dimensions (like, for example, for the ruler
bars), but I think it's more of an isolated case than the norm.
Most UIs won't set a button's height to 1 cm (or any other physical
size), because while such a size might be OK for a desktop + mouse
system, it would be definitely be too small for a UI in running a
television set and too big for a UI running on a smartwatch.
The discussion here is units, not physical units per se. And not every
application of QML is "drawing stuff on screen". For your application,
pixels is just as useless a unit to start from. Perhaps you need units
like Em or "strut" for the standard target size on your device or
something like that. I'd like it if it were possible to define such
units and use them in QML as a language feature.
