I wonder if you push your Password Store to GitHub? Its encryption is based on RSA with around 128 bits of security with current keys. It's unclear if it's going to stand beyond 2 decades.
I might be paranoid but with clouds I would be more comfortable with AES-256. If RSA is a must, maybe RSA 7680.
For the record there are quite a few new algos in GPG, most notably ed25519. While RSA 7680 offers 192 bits of security [0] ed25519 on the other hand is offering 128 bits of security. GnuPG 2.3 will have ed448/goldilocks available [2] and that should offer 224 bits of security [3] so in theory it should be better than RSA 7680.
I don't mind putting my encrypted passwords in a private GitHub repo but I understand the concern.
