Hi,
You may open RFS bug-report for sponsorship-requests pseudo-package [1].

You have received a link to RFS template in email from mentors.debian.net.

> https://mentors.debian.net/package/xsane
You should change "Needs a sponsor:" field here.
Also it would be a good idea to provide git repo for the package somewhere.
For example, at collab-maint on Alioth.
Best regards,
Boris
