I was able to get $firstname.{dev,app}. My idea was to deploy my apps at $app.$firstname.{dev,app} for dev and prod stages respectively. Now I only need apps that I can deploy there. I am still a bit reluctant to use either one as my primary email address (still relying on .org) because I worry that certain sites will reject those fancy email addresses.

I should say that I am more attached to my first name than my last name because the former is slightly more special and thus more "unique" (also it sounds cute when people say it in English).
