I like except for point 1 . We delegators are still experimenting with finding “honest” validators and this will make us more wary of going outside of the top 20 - 50 validators and using newcomers.
ATM we have no way of trusting newcomers , so little information about them or their setups.
BTW against increasing unbonding period … unless you do it over a percentage of holding over time. i.e. 1st 20% is 21 days , further 20% 30 days etc.
I would also like to see an unbonding option for say 7-10 days where you are penalised by losing rewards for x days.
