So my initial reaction is to vote against this. While I personally benefit greatly from staking rewards, I think it might be better to reserve SPS emissions for other areas of the game, such as ranked play. One other option to extend the runway, without extending the actual amount in the staking bucket, is to emit a % of the bucket each month. For example we could emit 5% of the remaining bucket and this could then create an essentially "infinite" SPS staking bucket. Btw if we chose 5% it would essentially cause a "halving" in rewards for the first month (see below) (I estimated roughly 45M left in the bucket from October onwards). Theoretically we could also put in some mechanism that slowly replenishes the bucket in a dynamic way (e.g. some % of SPS earned from some sales could go towards it or something like that; doesn't need to be decided right now).

The upside of this kind of approach would be that we'd extend the duration of the runway infinitely without increasing its amount.
