Totally agree. Acts like Spiritualized, Cassandra Jenkins, The Sabres of Paradise, Beach House, TV on the Radio, The Jesus Lizard, Stereolab, LCD Soundsystem, Anohni and the Johnsons, Kim Deal, Alan Sparhawk, Cap’n Jazz, Destroyer and Los Campesinos! wouldn't get booked if they had given up on the older demographic.
Weekend and Friday sold out... well before they usually even make the first announcement. Hopefully this means early announcements are going to be become the norm.
To address your "the fest no longer wants me to attend".
I attend Way Out West every year and I can say Primavera definitely still caters more to the older/alternative crowd than the Scandinavian fests in August. For example they are also headlined by Charli XcX and Chapell this year and they consistently have smaller lineups and less exciting undercards. They are still good alternatives for anyone living in Scandinavia though.
For major European festivals Primavera for me is still number one. Smaller niche festivals are the real options I think. I could easily prefer Roadburn, Outbreak or Arctangent.
