A maybe controversial comment: I'm for the abolition of the concept of coin-days entirely. That would, obviously, mean to follow the path that NXT and Peercoin clones like Blackcoin have taken, and for some may mean "throwing basic Peercoin principles". But afaik research on this topic, by various parties, has shown that coin-days is doing more harm than it is protecting the chain - because attackers, with this mechanism, can always accumulate more power with less stake and once they've accumulated enough power to be near an attack, can only be stopped with immense amounts of "staking coins".

The chainweight in Peercoin's security model was switched from coindays to PoS difficulty some time ago, coindays are only used to determine the mint reward.  So your concerns have already been accounted for in Peercoin.

Ah, ok, thanks for the information!

In this case, I think Peercoin - with the cold minting feature - would be fully prepared for the abolition of the centrally broadcasted checkpoints.

centrally broadcasted checkpoints.

Checkpoints were made optional via an easily accessible checkbox in v0.6.  Developers still believe checkpoints have value as a voluntary option, especially if we do something like multisig checkpoints in the future.  Turning this feature off is currently as easy as unchecking a box in settings>options.
