34419	Document django.contrib.admin.sites.all_sites	Adam Johnson	Edison Wang	"#27673 added `all_sites` in django.contrib.admin.sites` as a weak set of all sites instances. It's used by system checks to loop over all current site instances.

This set is also useful for custom checks and tests across all admin sites. For example, the parameterized test I just blogged about: https://adamj.eu/tech/2023/03/17/django-parameterized-tests-model-admin-classes/ .

`all_sites` has been stable since 2017. I suggest that we document it, so that it’s a public API that such custom checks and tests can rely on."	Cleanup/optimization	assigned	contrib.admin	dev	Normal				Accepted	1	0	0	0	0	0
