@icme Thank you for bringing this up again and reinforcing its importance.
I’d like to make clear that we’re quite aware of the issues this problem creates when integrating with 3rd party canisters and we understand it’s blocking certain use cases – this is why we have indeed bumped it up our priority list (if you check out Sam’s last roadmap update, you’ll see it there, it’s listed as “Safe canister upgrades”).
As you mentioned, I expect that now that the BTC integration tail work is wrapping up, the execution team will have the cycles to pick this up soon.
