Okay, I didn't read that post because it didn't change the fact that I - due to whistful thinking - thought that the new rule meant teams would be allowed to skip more races, not fewer.
And I certainly didn't expect a rule so *** stupid that it doesn't even allow teams to collectively declare a race not worthy for WT status by a majority deciding to skip a race.
But I guess UCI really wants to make sure a majority of teams ride their pet projects...
The UCI decide which races get WT status, and the only way they will revoke their decisions seem to be if the organisers either don't put the races on TV somewhere or, which is probably the most important to the UCI, fail to pay for their licences.
