If removing PoS would help the developing process I can see a point in sacking it. But please lets not increase the volume of new coins created or the maximum supply.
Its inevitable.
Removing PoS will increase volume of new coins created (both PoW and PoB.)
Increasing PoS diff. will increase volume of new coins created (both PoW and PoB).
Their is no way to keep the current daily coin supply the same unless PoW block creation time is increased.
If we turn off the POS the effect is to go back at the first rate (before block 16k) and if I remember it was not bad. Just not to change anything else.
