I don’t think we ever had a complete proposal for these tags, they just got into existence. Now they are used over 1,000 times compared to about 40 socket:usb in differing spellings which are not even useful because the actual type of connector is missing.
If there is the wish to change them, then there should be a proposal for this.
IMHO, I don’t see a reason for this: There is no harm done in having sub-categories instead of one huge list. All those socket:device form a proper sub-family of power connections - small, low-voltage, non-rugged, universal power delivery. Compare that to the regular mains-connected high-voltage power outlets or the various specialized charging connectors of single vendors.
The term ‘device’ might not be perfect, but tags don’t have to be a perfect match to their dictionary definitions, they just need to be a recognizable, documented description of one well-defined property.
