What's the reason for including this snippet? Presumably we want to encourage people not to add this config if they don't need it, especially since the API is expected to change

[scholzj]

@katheris I won't lie ... the AI included it there and I did not see any reason why not to include it. 🤷 Do you want me to remove it?

[katheris]

I think I would prefer to remove it, just because to me it adds unnecessary length to the docs that people have to scroll past

[scholzj]

Ok, removed. Please have a look if it is ok now.

@katheris @ppatierno Anything more on this? Thanks.

[katheris]

Thanks @scholzj
