[Tagging] Re-using the marker tag for survey points

Hi, a suggestion on the Survey Point proposal (https://wiki.osm.org/Proposed_features/Survey_Markers) was to re-use the tag marker=* instead of creating survey_point:structure=*

This sounds like a good idea, but there are some issues:
* Some values of survey_point:structure= are not valid for utility poles, and vice-versa, so the marker=* tag would become complicated - some values can only be used with certain tag combinations.
* It will be difficult to create presets in editors like iD because of the foregoing point – fetching a list of common values from taginfo wouldn’t tell you which values are valid for which features.
* there will be a tagging conflict for survey points on the same node as a utility pole, since it’s not clear what marker=* refers to (like the service=* tag on roads/railways)

So what does this mailing list think of using the marker=* tag instead of creating survey_point:structure=* ?
To me it seems like it’s creating more complexity and confusion...

Best regards,
