Hi,

There is no discussion as of now.

Currently, the 'repair'-tagging is a mess. There were multiple wikipages, each indicating their own schema to indicate what is repaired where (namely "repair=yes|no|only", "repair=<item>"  "<item>:repair=yes" and "service:<item>:repair=yes"

This changeset is a partial cleanup by changing all "repair=item" into "item:repair=yes", but it definitively isn't the end of the cleanup effort.

Note that part of the problem here is that some special cases are not documented well. For example, you indicate "service:vehicle:tyres_repair=yes", but this one has about 200 entries; whereas "service:vehicle:tyres=yes" has over 9000. 

If you know of other such special cases, please, link to them in the wiki: https://wiki.openstreetmap.org/wiki/Key:repair
