Creating own config or macro pages

Hi,

this is just a question related to my missing knowledge.

On some plugins like the OIDC plugin them are talking about that I can create pages with a configuration object in there. The part with the object I understand, eg, creating page, save, then edit objects and add objects I wanted.

But what I’m a bit confused about (or better: unsure) is where to create such pages. Is there a recommendation where to put individual configuration pages? Eg, under /bin/admin/XWiki/ or is there a specific namespace for such individual config pages?

Same for self-written macros. Whats the recommended place for creating pages containing a macro? Or is this simply made by design that every wiki admin can decide where to store such things?

Tnx
