Shorter block intervals means higher orphan risk, also, you would need to wait more confirms for the same level of certainty.
What I refer to are all the very fast blocks that occur when hash goes up.
There should be a hard limit mechanism to enforce a 10minute minimum time between blocks.
or Why not ?
Why not: Disincentivizes competition, could just result in miners shutting off their equipment for ~9m after every new block or easier attack vectors
That is what the automatic difficulty changes aim to achieve.
Fails "to achieve".
A simple automated block rejection
based upon timestamps less than 600seconds from the previous block.
Instead we pay for empty blocks in diarrhetic spurts.
