Thanks so much, Henri, for the quick reply and the excellent news that this is supported.
Just one question from your example: am I correct that, to make this work, we have to apply both step 1 (relying party override) and step 2 (client metadata change)? I assume so but just wanted to make sure that both steps were needed rather than one of the other.

I don't see anything in the OIDC extension docs about this, so I figured I'd ask. Does the OIDC extension support PKCE and the use of a code_challenge parameter in place of a client secret in an authorization request? This is, obviously, in the context of mobile apps and not having to embed the client secret in the app.
Yes, PKCE is supported since 1.1.0. I’ve just added a case example at the end of the following Wiki-page:
