Tl;dr nope no key rotation.
But its being considered and worked on.

Thats good to know.
Curios to know also if it matters how your keys where generated for example, if you used iris.to vs snort etc. Are you trusting those providers due to the fact they generated your private keys?
Dont quote me on this but I think most clients try and do everything as locally as possible. Keeping key genaration and such off of their own servers.
There are exceptions like ZBD that dont allow you to get your private key. I would consider yourself compromised if you logged into ZBD.
