I would really like you to expand on why adding
"riser=power_line;tele_communication"  would make things difficult to
map. Though I think it might be hard to visualize making accidental
deletions a worry.

Risers seems to be pretty easy to map, but under ground cables might
not be quite as easy (since even tunnels are hard).
