Hello Fernando, I was just advised about this mailing list so have joined yet another ! (sigh...)
Thanks for pushing this issue, my concern is that people's lives are potentially at risk here. While I am not really committed to using tracktype= as the trigger, on the Austrialian mailing list we had a long discussion about it and, more or less, concluded it was the best option from a poor set. The options were summarised on http://wiki.openstreetmap.org/wiki/User:Davo and in the Discussion section, you will see that I quoted some numbers, dating back to late 2012 showing that there are twice as many tracktype= tags used as surface=unpaved. I think the biggest problem with surface= is that it has so many possible values. The original approved definition of tracktype made it clear it could be used where highway= other than 'track' and it is widely so used but I'd have to download all the data again to get fresh numbers on that. I wanted to extend tracktype= to three further values representing 4x4 only roads. But could not get a committment from enough people to get a vote going. But, all that aside, the real need is to see unsealed roads rendered in such a way that people are warned and not put in danger. I would be happy to support and sensible trigger tag. Except, perhaps, smoothness=, I will not describe the pretty little road I live on as "horrible" !
