Whitelisting the To: address is something that SpamAssassin does.  It
allows many emails sent through mail forwarders to be whitelisted. 

If you whitelist the "To: " corresponding to your address at the forwarder, 
you will whitelist all the spam sent to this address, won't you ?

Yes, this is also true for SPF-classic (Unified-SPF/MAILFROM) and
SenderID (Unified-SPF/PRA).

Unless you rely on the forwarder itself to perform the checks and reject 
failures in the first place...?

Right, mailing lists and forwarders need to do a good job of spam
filtering and in my opinion, that includes SPF checks.  However, if
someone chooses to use a poorly run forwarder, or simply wants no spam
filtering done for the forwarded address, that is up to them.

Did I miss something ?

Nope.
