Tacotime who is very experienced and respected in the community, has been involved with many coins, and is a very serious cryptocoin developer himself (MC2), is adamantly opposed to the ring signature trimming for example.
.....
Tacotime was also criticized bbr aliases idea. Now you implemented aliases in Monero
In a different way that addresses the issue of namespace management and squatting, which I'm pretty sure is what we said we would do at the time. It has other tradeoffs, as do all implementations of anything, I suppose.
Anyway, can you say at least one real argument against removing RS under checkpoints ?
It isn't possible to independently verify the chain. This significantly elevates the trust model for checkpoints from choosing among valid chains to trusting that the chain below the checkpoint was valid before being trimmed. Again, tradeoffs....
