Uh… what? How does this achieve tail emission… doesn’t it just delay the end year of 2140 to an unpredictable time?
Hard no
it doesn't simply: delay it delays only - if the security of the network is still degraded due to previous halving just before the next halving
so, no degradation = no delay
so, this may achieve tail emission or not - and achieve it indirectly and all depends on: if the network security requires it or not
