It's not just a rendering issue, although that's the topic of discussion. It
makes it much easier for editing and later processing (it's easy to split a
way, not as easy to recombine it). Currently, if you want to add or modify a
tag on a long way, you have to click on each section to change the tag. In
the degenerate case, you'd click on every single segment. I realize it would
require good editor support, but it's disheartening to see the "we've always
done it that way; why should we change?" crowd coming out already on a
project this young.
