Well the UCI is like a mini version of the International Olympic Committee - borderline corrupt, pretty ineffective at anything and barely useful so not astonishing they don't do that.
I suspect the promoters try to keep away from the UCI as much as possible.
There have been a few attempts by the pro-teams to improve the situation via Velon[1][2] - apparently you can get live race data from them - but nothing that has really solved the problem.

Figuring out that I need to subscribe to GCN+, Peacock, and Flobikes in the US was no small feat (and it changes from year to year!).
