Are there any other clients that support this?

This is the vision of improving safety and it probably will push customers to also improve security against attacks.

It is already very good to have a fish regularly updated , so if it can be even better it will be beneficial to everyone :)

CFB alone does not add any security at all. The weak link is authentication. I may or may not be working on a FiSH-based OTR implementation that would expedite security levels to "NSA-proof if used correctly" - for queries. And since OTR is an established standard, it's also interoperable with other IRC clients. OTR is not currently available for group chats/channels (you may at least use the cbc: key prefix in FiSH 10), but people are working on making a that available as well.
