This proposal by Stereo is nothing really new.  Just a alternative to 
routing which has been around since relations were introduced. 
Definitely not 'PTv3'. The 'via' option appears almost as difficult to 
maintain as including ways.

It means PTv2 tags aren't required as there are existing tags performing 
the same job.

No. They are preferred because they simple to comprehend, accurate &

PTv2 isn't supported because it's not abundant (people get bored of 
adding them after a couple weeks)

No they don't. They can use just the original tags. PTv2 tags are pure

The original tags are here to stay because they work. PTv2 is a 
*separate*, *independent* scarcer schema running in parallel that adds 
nothing over existing tags.

It is only PTv2 which is the mess. Even those who conceived it are 
confused by it.
