In the industry we have to consider all of these aspects and bearing selection is a major part of the design.
I don't know what speed vexpro hex bearings are rated for so I can't say exactly if they will work or not. However since they decided to withhold the specs I would assume that the bearing won't work.
I am going to let you in on a bit of info that 5817 learned this season. We changed out the hex bearings on the shooter with bearings from McMaster (who give specs on their bearings) with an appropriate rpm rating, our shooter spun around 1000 rpm faster with just a bearing swap.
I don't know why vexpro doesn't give us this info, I am assuming it is either 1: they don't accurately know, or 2: posting the data will harm their sales.
Let's say that the bearings have a low speed rating this could affect uses in a lot of frc applications besides shooters perhaps even some gearboxes. Vexpro also knows that students might not look into specs and thus never bring up any concern.

1. It doesn't look like McMaster sells 1/2" hex bore bearings, or anything close to thunder hex size, so it sounds like you might be comparing apples to pineapples or something.
2. Have you tried asking anyone at Vex for ratings, if they're that important? I suspect the main reason the specs aren't listed is because they're in excess of nearly every FRC application.
