Dear Salvo,
I may not have been in contact with you on the mailing list but I really feel sad for missing a sponsor.
I am not aware of which direction Debian is heading regarding welcoming new developers.
It is already quite difficult to gain a sponsor for Mr. Nobody through requesting other DD's unless you live on the same street as the sponsor by chance or if the sponsor happens to be the one who motivates you to be a debian maintainer. This is the only way you can build a chain of trust and there is nothing wrong with it.
I hope and pray that you come to a resolution soon.
Regards,
Shahrukh.
