I disagree. Either there is a bridge / culvert in reality, and in this case
why wouldn't we want it in OSM, or there isn't and then it is a simple
error waiting to be corrected.
Which trouble do these elements cause? I realize they make it harder to
apply modifications to long (i.e. probably more pieces) ways, but on the
other hand, casual mistakes also don't extend very far.

Think how much work it is to construct a culvert or a bridge, those will
last typically for a long time (also because they are there for a reason),
and compare to how much work it is to put them into OSM (2 nodes, split,
add one tag). Is this still a real problem?

If you are not interested in mapping them, don't do it, but please do not
invent a tag that encourages not to map them.

Cheers,
Martin
