I agree fully. Also:
- The JOSM validator whines about the segments being used twice*
- It's considerably trickier to select one thing or the other in JOSM*
- Say you're marking a forest at the side of a road - the forest
doesn't begin exactly at the side of the line running through the middle
of the road, it begins some metres away.
- Sharing segments makes things more difficult if either of the
sharers changes its position
The two (*) items could be considered bugs - but in the majority of
cases where the validator warns, it's warning about a real problem. It
would be a shame to pollute this list of real problems with unnecessary
warnings.
