did you read the proposal ? look at the natural part of the picture https://wiki.openstreetmap.org/w/images/thumb/e/e6/Waterway_flows.png/500px-Waterway_flows.png it's not a man_made=pipeline I have explored several siphons in my life, but I have never done caving in a pipeline :) >> and it's a good thing to have a continuity "of water" with waterway=* > But pipelines can and do contain water ..

We already do this for many other objects e. g. highway <> surface: you have a continuity of highway=* tag even if the surface of the roads changes and in case of tunnels or bridges. this is exactly what the proposal wants to do: a continuity of the waterway=* tags even if the materials/man_made/usage/tunnel change. With this clear structure, you can use water flow datas separately from material datas.
