Hello Gazer, this has been discussed in this proposal I shared previously: https://wiki.openstreetmap.org/wiki/Proposal:Power_circuits_routing#Less_tagging_redundancy_between_lines,_sections_and_circuits
It has been reviewed and voted.

It's better to leave a single information at one place and frequency is definitely a matter of circuits and logical layer. We currently make progress on editors to improve presets and reduce the hassle for mappers.
