LGTM. This was added in #7570, I see no discussion there on this being made private for any specific reason, and our policy today is to have all configuration as part of the public API

@lpegoraro can you add a changelog entry?

[jpkrohling]

LGTM. @lpegoraro, can you please add an entry to the changelog, by adding a new file to .chloggen?

[lpegoraro]

hey, just added. not sure if it is by standards, let me know if anything.

[lpegoraro]

Do we need anything else?
I cannot merge.

Let's rename the struct first, since we have the chance to do it now comfortably

[lpegoraro]

any news on this?

[mx-psi]

Can you merge/rebase main, so the tests pass?
