I just posted in the JS forums, I'm hoping that since it is in beta they can make adjustments before finalized.
I would also urge the MVC team to look at addressing the issue that does not require all kinds of hacks using js and special server code. Paging should be a built-in property-based functionality. It is a basic requirement for a grid.
Syncfusion missed the boat here. I won't repeat everything, but what I posted in the JS forum applies to the MVC grid as well:
