I think that the orient attribute should be used for <progress> and
<meter> too and those elements would need a third state in addition of
'vertical' and 'horizontal' that would be 'square' (or 'round' or
'center', whatever is the best name). That would allow spinners for
<progress> [1] or round <progress>/<meter> UI like [2].

Using a vertical attribute would hardly solve those use cases whilst the
orient attribute would deal with them quite easily.

I also agree that 'auto' is a pretty undesirable behaviour. As far as I
know, this is the behaviour <input type='range'> is requested to have
and no one implemented it. Microsoft expressed their concerns about it
two years ago to www-style [3].
