Kinda does if they want to run bicycle races that aren’t affiliated with the UCI, doesn’t it?
I honestly cannot understand how the UCI’s involvement impacts anybody other than the pros racing for the win/national/world champs jersey, and even for them it’s only due to standardised equipment (or, more correctly, limits on what might be able to be used, e.g. no aero bars. By the way, where do aero bars fit in the spirit of gravel?) and drugs testing, to level the playing field.
When I do a club race on the road or mtb - both of which are run by clubs affilated with a national organisation, ergo under UCI ‘control’ - there’s literally no difference to doing a gran fondo or MTB marathon race run by a private promoter not affiliated with anybody, except the non club run events are usually heaps more expensive. Both are great, they’re just different.
