I don't know why we would celebrate this.
The children of our EU friends living here still have their fom, when they leave school they'll be free to live and work in any one of 31 countries (I'm pleased for them) our children won't be. I've heard 'EU passport holder' is starting to appear on CVs now as it makes people a more attractive employee in certain sectors.
Oh and I grew up in one of the most deprived areas in the country on state benefits attending a failing school. I made use of fom in my youth and it gave me opportunities young people in my situation won't have anymore. It's not just for rich people.
