This already exists in the form of the odbl=clean tag. Anything tagged
this way will show up green in Frederik's map. It is documented here:

If such changes can be easily picked out by changeset, then the whole
changeset could maybe be considered clean. This is what has been done
with the TIGER name expansion edits in the US. The user has declined
but explicitly allowed all of his changesets tagged with bot=yes to be
relicensed and Frederik's map takes this into account as documented
here:
http://wiki.openstreetmap.org/wiki/Quick_History_Service

Of course we can't just go rampaging through all changesets and
marking them as clean... but it is a mechanism that is available. Of
course all this is assuming that the final process will honor these
same rules.
