About the requirement of delegating personnel when initiating a pull request

[AlexKuai]

Describe the feature

In the current process, when a user initiates a pull request through the fork warehouse to select a delegate, the user must also have read / write permission to the upstream warehouse before selecting a delegate.

If the user has only read permission, the delegation list is empty.

However, granting read and write permissions to some users violates the security of the upstream warehouse.

Describe the solution you'd like

It is hoped that even if the user has only read permission (no write permission), he can select a delegate with write permission when initiating a pull request.

Describe alternatives you've considered

There is no alternative at present.
