You point out the problem with this:

tracktype is ignored on everything except highway=track

You would have to modify this in the rendering anyway.

As 4wd_only can apply to any highway= tag it is more appropriate.

 From memory this was part of the original discussion when 4wd_only was 

Additionally my feeling is that because it's not rendered it's not used 
and Australian understanding of 4WD is definitely different to the 
European understanding.

Have a look through the original proposal on the wiki and also the 
smoothness discussion
