24456	[PATCH] Power circuits relations presets and validation	francois.lacombe	team	"Dear all,

Recently, and after several years of improvements, power=circuits has been reviewed and approved.
https://wiki.openstreetmap.org/wiki/Proposal:Power_circuits_routing

I encourage to use relations to map power circuits over physical level of power segments (line, cable, minor_line...).
It's a robust solution to avoid values lists in some keys like frequency as mentioned in #22633 and #22915.

Currently in JOSM, discouraged tagging with type=route + route=power is part of presets.
It should be move to a new category and replaced with type=power + power=circuits relations with same tagging completed with new topology{linear,branched} key.

https://wiki.openstreetmap.org/wiki/Key:topology
wires=* key should not be used on power=circuit relations.

Roles are also changing. A power circuits expects `substation` and `section` as roles instead of `substation` and `line`.

It is possible to create relations involving discontinued lines as some segments may be missing at the moment at which the mapper intends to link two substations.

Finally, as per https://wiki.openstreetmap.org/wiki/Proposal:Power_circuits_routing#Less_tagging_redundancy_between_lines,_sections_and_circuits, a validation warning should be raised when both power=line and power=circuit relation it may be member of expose frequency=*. This information should be on relation only.
