They don't need to be, since it's enforced at the OS level. Users can limit permissions to individual contacts regardless of whether iOS apps have been updated to explicitly handle that use case.

I meant updated yo the newer nicer replacement UIs.

For example I know Slack still doesn’t use the single picture picker. They still want access to everything.

So iOS lets me limit what they can see, but it’s still a pain compared to just letting me pick the one picture I want.
