You might be surprised.  As well as people who are "interested in 
pipelines" they're often also a useful navigation feature (if not always 
as obvious as, say, an overhead power line).  Near me in the English 
midlands features such as the Derwent Aqueduct and underground fuel 
supply lines become very obvious once you start recognising the features 
- and they have very different features on the surface because of the 
different thing being carried.  In many ways it's similar to the 
electricity supply tagging changes that have happened over the years - 
those changes didn't always appear to consider the usefulness of those 
features to people using them for navigation.  In other places 
overground pipelines are very important to people interested in wildlife 
migration, for example.

To be clear, I don't think that anyone's criticising the change itself, 
just the notification of it.  If people are using existing data they 
need to get some warning that it's about to change (separately from the 
more "in depth" discussions on the tagging list about how best to tag 
something new).  The only thing that the "proposal process" in the wiki 
says about existing data is "never use a vote result as a justification 
for large-scale re-tagging of existing objects".  Now two pipelines 
clearly isn't "large-scale", but it would still have been nice for data 
consumers to know that the change was happening.

Cheers,

Andy
