true, but it doesn't change the fact that it currently would be worth $55
or that posts that were made 7 days ago nearing payout showing $10 are worth $55
The display should be accurate to the moment with no promise about the future
Your second point about downvotes is true but quite niche. It would happen if Steem price is high anyway. Basically the increased SBD price is just as real as an increase in Steem price enjoyed by the system and it should reflect that.
I feel that overall, under displaying rewards is just a missed opportunity to attract more users onto the platform. Regardless of how likely it is that SBD will normalize, the fact that rewards are currently 5x more than the displayed amount is very real.
I don't think it's niche at all. Its a daily occurrence as someone who's constantly involved in steemitabuse; I've seen this "deserve" mentality constantly. I think you might be discounting people being attracted only to the $$$ and then leaving because they didn't get what they were "promised" by the system, if the reward changes.
This is actually not exactly true: the increase in steem price does not immediately affect the price of all posts. It has something akin to an averaging function of the price of steem over the past week or so. So if there was a spike to 10x the value of steem, we wouldn't see posts go to 10x right away. They would slowly increase over time to reflect the change. (Though, maybe we could do the same with value of SBD, and have witnesses report SBD/USD.)
