Can't imagine they'll make a big deal of it. Plenty of things in the peleton that aren't widely available to the public. UCI largely turn a blind eye to it.
As I recall the rule is that it's supposed to be available to the public within 9 months of being used for an event. I imagine they have that much kit to keep track of that it would be a massive pain in the arse to keep track of it all and see what's available where and to whom and on what scale, so unless it's something is creating a really egregious advantage they probably don't fuss over it too much. Besides, with some things it gets a bit silly, like one off parts that cost thousands. Sure, you could stick it up on your website and say it's available at a massive cost and has to be custom made in single lots and then no one will buy it anyway.
