I disagree, an important requirement of tagging schemes and mapping
best-practices (it's not just about tags here, but what you apply them
to) is that they are easy to maintain. The map *will* get updated, and
you have no control over the skill level of the person who comes after
you. So you'd better make updating the map easy for that person.

That means in this case "don't be lazy, split the way so that only the
required portion is tagged with maxheight". That same reasoning can
help decide between otherwise-equivalent mapping practices, such as
when to use overlapping ways vs mutipolygons.
