Funny the things that make you scratch your head.
Here's my take, I'd leave them on. They're more than just dust caps. Think of it this way. I used to have an old paint brush spinner. I would stick the brush handle in it and stick in a empty buck and it would spinn the excess paint off the bush bristles.
If you stuck a joint without the seal, let's say a driveshaft. It would be exposed to dirt sand and the likes. But.. would it spin the grease out of the joint trunnion?
If it's inside, will it take on grease, or lose grease, or neither.
For me, the low hanging fruit is leave the part as shipped and install it.
Good luck; and have fun!
