The capability is just an incremental change over existing chart, hence I have not submitted a formal proposal.
I have an implementation that follows the outline of the mechanics described in the documentation (https://docs.temporal.io/docs/server/configuration/#tls) , and serves the use case . I will contribute a PR if the feature request is prioritized for implementation

Hi, I made a PR a long time ago but closed because they wanted to revamp the project ...
#162

(I'm still using it for myself and our organization because TLS is a prerequisite)

@lerminou Coming accross the exact same issue at the moment and need to setup mTLS for the frontend SDK as a prerequisite - Will take a look at your PR 👍

@underrun does it make sense to wait for the new helm charts, is it likely that this feature will be added to the existing helm charts, or should we in the meantime customize the existing chart ourselves locally (similar to PR #162), if we need the feature?
Thanks for any feedback :)

What is the chances the original proposed PR can be re-opened? This proposal is now closed, which leads me to believe nobody internal is working on it. temporalio/proposals#42

I believe all aspects of this are now supported by the current chart. Please re-open if this is not the case and I will work with you to get whatever is missing sorted.
