Standard identification tag is indentify-this-xxx so I suggest we keep identify-this-instrument so it is probably not necessary to keep both.
Should we burn instrument-identification?
Having enough points for identify-this-instrument, I could (only) suggest a merge with instrument-identification. People should vote for this merge now.
But I'm not sure which one will be the master though. I mean, it should be identify-this-instrument, but I don't know how to actually do it.
