For potential consideration:

g=rwX could be an option to limit adding +x to directories and where a user already has x.

No. Those are completely separate issues. As stated in the description: This PR solves the issue #945. In the description of the issue I posted a very detailed the description, which should make the difference clear.
But in short: This PR and #945 tackle an issue while importing a private key into the gpg keyring only on some jenkins agents (mainly the nodejs agents). The issue you mentioned tackles a problem that helm secrets sometimes can not find the right key in the keyring on a agent that is not affected by the problem described in #945.
