It is also possible to consider a model where only new investments have the shorter lock time, but existing SP/VESTS still have to power down at the existing 2-year schedule (possibly to repower up under the new schedule).
This will create an environement where users are not equally treated in the system, bad precedent imo.
It will also mean that current users can't take advantage of the new feature ( reduced lock time period)
Also I am not sure why you would want to still lock people for so long, what would be the point of that? A reduced inflation means that we no longer need to prevent people from selling their share because there will be many willing to buy on the other side.
I didn't say I wanted to do this. It has advantages and disadvantages.
