The maxheight=* tag maps the physical limitation, not the sign (which
can be absent or even wrong). Tagging maxheight=none really makes no
sense.
no, the maxheight tag maps the legal restriction (typically derived
from a sign, in absence of a sign might be implied by other legal
provisions). For physical restrictions use maxheight:physical (in some
countries this is even signed). For the actual clearance height we
could still use another tag like "height" (maybe better not, as this
would IMO imply the height of the road, i.e. from the surface
downwards) or more explicitly "clearance_height".
in the US, the default behavior is that the signed max height has a
couple of inches to spare.
if there is no margin then it's considered an actual maxheight which
naturally would map to
maxheight:actual
i have no idea what usage is in the UK
