Agreed. Signs are useful for the driver and the mapper, but they don't
change the physical reallity of the height restriction. If you don't
have a good maxheight value handy (either thanks to a sign or via your
own measurement), just tag an approximate one (erring on the low side
for safety reasons) and add fixme. Or if you don't trust yourself
doing that, don't tag anything.
