I can add the possibility to have custom data stored in a map. But how
should we store it in the wiki?

What I propose for the extensibility:
- anyone can extends the Wiki class.
- each module will have its own XWikiServerClassDocumentInitializer, that
add custom fields into the XWikiServerClass document.
- the minimal XWikiServerClassDocumentInitializer will only contain a few
fields.
That's not extension. I was expecting a generic way to access and
modify descriptor properties. The "extensions" you are talking about
are going to be completely independents modules that directly
manipulate xobjects and they will have to provide their own complete
API, do there own caching of descriptors etc, extending Wiki class is
pretty useless for them.
