Enhancement: ratingMin

I have loved congress.org.uk for a while and use it to run my own events.
I've tried to run a minRating event system where one of my sections was 1750-2400, but that was disregarded multiple times. There's already a function for rating caps, so I am naively guessing it wouldn't take much to add in a Minimum rating requirement? I'd really appreciate it if you took the time to.
Cheers
