Anyone remember the days when lens flares were considered unprofessional and filmmakers were taught to avoid having them?
Well, no. If such days ever truly existed, they were before my time and yours.
Basically, if you tried to set up your shot to avoid lens flare and ended up with lens flare anyway, then that was inept and unprofessional. However, if you deliberately set up your shot with the intent to produce lens flare and you got lens flare, then it was an acceptable artistic choice and entirely professional.
