Thank you for polishing this 😄. I'm wondering what makes you change your mind. As you know, I raised some issues from the original PR, @hvanhovell . Anyway, +1 for this direction.
Removing them caused friction

@HyukjinKwon @cloud-fan this returns null. I was expecting a NoSuchElementException here. IMO this is a bug. WDYT?

yeah, i think it should. def get[T](entry: ConfigEntry[T]): T isn't an API so I think we should be fine with changing this behaviour too.

What changes were proposed in this pull request?
This PR adds support for ConfigEntry to the RuntimeConfig interface. This was removed in #47980.
Why are the changes needed?
This functionality is used a lot by Spark libraries. Removing them caused friction, and adding them does not pollute the RuntimeConfig interface.
Does this PR introduce any user-facing change?
No. This is developer API.
How was this patch tested?
I have added tests cases for Connect and Classic.
Was this patch authored or co-authored using generative AI tooling?
No.
