Scheduled inflation became irrelevant a long time ago, with the DHF being denominated in HBD our inflation rate will depend on the price of HIVE.
This was a conscious decision with the HIVE fork. We removed some supply temporarily, and converted it to HBD. As those can be converted back to HIVE, the supply rises when HIVE price goes down.
But even as things are going now,we have about one to two years left before our supply reaches that of the chain we forked from. It's disingenuous to claim that the funds that were always supposed to return to the supply would be some kind of excess inflation.

You should of course always ask yourself if a proposal can add value. Everyone will evaluate that differently, but you can be damn sure that the voters with big influence do it too. If things work out as hoped in the end is a different story.

All in all, I don't see this project as helpful. It misrepresents individuals influence, ignores the founding history of hive and the DHF by sticking to the inflation schedule of a dead blockchain, and certainly won't help to make HIVE more valuable.
