Pretty much as what @nucky.sol already commented. The debate about the jupuary has been going for quite some time now. Bigger stakers were afraid that they will be taking the hit regarding dilution, but with the recent adjustments, even majority of bigger stakers approved the conditions and voted yes for the most recent proposal.
Allocating some part of Jupuary to stakers resolved the issue as it works as a protection for their locked capital. 
You can find the most recent proposal in THIS thread.
