I'm going to agree with DazTC on this one. I don't think this Alex M.O.R.P.H. remix fits the criteria to be considered a "classic," and in fact most tracks from 2011 aren't going to be classics.
For me, the nearly arbitrary cut-off is 2010, which is when the modern tech-trance sound started forming. I would definitely consider John O'Callaghan - Striker [2010] and Ummet Ozcan - Vimana [2010] as classics, but this Alex M.O.R.P.H. track is just a regular 2011 track. If anything, the other remixes of Far Away should be posted.
Now, you mentioned that in 2010 it would have been fine to post a track from 2001. The thing is, in the previous decade trance evolved a lot and went through several different styles. In 2010s trance largely stagnated, and apart from the progressive psytrance movement of the early 2010s and the commercial psytrance from Vini Vici & co. from around ~2015 there have been almost no changes to the genre. It's followed essentially the same formula since then.
IMO the 2011 track most qualified to be considered a classic is Eco - Under Paper Skies, due to how unique it is.
Of course, all of that is just my opinion. Not trying to be the trance police (after all, who can truly determine that a track is a "classic"?). Then again, when a track from then sounds just like what we can hear now, it's difficult to take it seriously as a genuine classic.
It's good that we are having this conversation so early on.
