I hardly think this is being rushed at all. This is the 3rd poll we've had regarding CBR (1 2 3), and each time CBR support has been overwhelming in both vote weight and vote count.

I do understand however that this will make it more difficult for newbies to stake and therefore get their Research Rewards, and that has been addressed with the assumption of the implementation of MRC (1). You could argue that it would be ideal to implement MRC before CBR, but in that case in the time we have MRC but not CBR, there is almost zero incentive to run a node. At least to me, that is not a risk I'm willing to take.

We could of course release both CBR and MRC at the same time, and I would defer to the devs opinion if that's an appropriate course of action. I'm unsure if that would be considered to big of a change for 1 release.
