I'm not a fan. As a witness I wouldn't vote against the SMT proposal because this is included, but I think it's bad for the network to change it. Part of what makes Steem a community is that people can't just up and leave. If you have steem powered up you're going to be a part of this place for 13 weeks. I think it's part of why steem has a culture of "we all go to the same moon," as opposed to "sorry suckers that token is going up slightly faster so I'm leaving." It happens anyway, but there's a bunch of people that'll post here up until the blockchain flatlines.
I do think it's a real concern to speculators that people can't get their money out quickly. That answer is simple. Buy Steem, nut don't power up. The question I see is does it hurt investment? My guess is that there's more problems seeing the utility of Steem and getting in and out is a tiny side show. So, rather than rush a "simple fix" that I believe will hurt the community let's move it until after the hardfork and make it a burn case.
In a different version of this, Steem still has a 13 week powerdown, but you can burn some of the steem you would otherwise get if you wanted it to happen faster. Adds a burn case for steem, doens't hurt the community, and is a step closer to investor/trader friendliness.
In the larger scope of things I don't think a minor tweak of this property will drastically change things for the better. What will change things for the better is adding apps, usecases, businesses, and communities of people that are able to use Steem to make money, make a point, grow an audience, play a game, or some way that this place adds more value to their life than having dollars in a bank account does.
