Thoughts on use of another person’s email as a recovery option in Protonmail

Before you all think I’ve gone completely doolally, let me explain! Until today I have a QR code set up and a recovery phrase and a recovery file. I am reviewing my all backups and security etc and have been thinking about the fire scenario when you lose everything. Obviously for this to be an issue, my offsite backup method would have to have failed too, (this is manual, not cloud, so not impossible that the portable HDD would happen to be at home at the time of the hypothetical fire) and the trauma of it all will also have made me lose my memory so, in this hypothetical scenario, I’ve forgotten my Proton password. So all in all quite an unlikely scenario! Nevertheless, I am of a nervous disposition, so just having the “minimum” recovery options is making me jittery. I am the controller of all things financial and IT related in our house, so also wanted to make sure that my husband could access my Proton account in the event of my death so have set him up as an “emergency contact”. He also has a Proton email which is already connected to my account anyway as we have Proton Duo. So if I’m doing that I though I may as well set his email up as a recovery email for my password? I trust him implicitly, we have full insight into each others affairs, money, health etc and have codes and passwords for each other’s devices which we both use with gay abandon. In a torture scenario, he’d hold out much longer than me so not worried there either Am I missing anything here? Any issues with doing this that I haven’t considered? Many thanks
