That doesn't necessarily follow.  For one thing DD's voice says that
she has agreed to the pact in OotP, doesn't it?  Also, once Voldie had
fallen that did not appear to be a threat and certainly no DEs would
know where HP's muggle relatives lived yet.

Sirius would have taken in Harry had he not been implicated in Harry's
parents' murders, not Petunia.
