I don't see that there's anything wrong with adding mkgmap: tags
to the OSM database. After all, the wiki plainly says that you can put
any tag you like on a node/way/relation. I have been tagging roads that
look like flare roads but are not actually flare roads with
mkgmap:flare-check. This stops mkgmap whining about them. I also use
mkgmap:dir-check to tag roundabout segments that would otherwise show
up as having the wrong direction. The presence of those tags doesn't
have any affect on how the roads are rendered/edited. The only "crime"
I have committed is that I have yet to document the tags. 

But those test disabling tags are quite different in concept to tags
like mkgmap:unpaved or mkgmap:ferry. I agree that those tags do not
need to be added to OSM data.

Cheers,

Mark
