Hi Jospeh

This proposal is an attempt to bring consistency in markers mapping, in two
ways :
- Provide a common concept to tag them all.
- Free pipeline=* from some features unrelated directly to pipeline

Second point should encourage a mapping good practice I didn't have in mind
in previous pipeline mapping evolutions : the marker shouldn't be part of
the pipeline way directly as it warns about the presence of pipelines in a
given range or distances.
Just like road signs should get their own node beside the road instead of
be part the highway way.
To me yes, we should encourage to use marker=pipeline instead of
pipeline=marker prior to the last gets *really* used.
29k features is less than the whole amount of pipeline markers we have to
find in France (which is a small area).

All the best
