New permissions to log in via GitHub?

I'm trying to sign in to my account via GitHub with a new browser profile, and it appears to be asking for new permissions:

Is this a deliberate change? If so, why are the new permissions (i.e. access to private profile details) needed?

This application will be able to read your private email addresses and read your private profile information.

The additional permission is user:email, which grants Greasy Fork镜像 access to know your email address, even if it is not public on your GitHub profile. Email is required for making an account on Greasy Fork镜像.

But I'm not trying to make an account, am I? I'm just trying to sign in. (I'm using my old profile to post this, which is still logged in.)

Presumably you have access to my email address already or I wouldn't have received this notification?
