As others have pointed out... the trouble with that one is that it eliminates the chance of a pardon for someone who is truly innocent (e.g. if evidence is found exonerating them.)
That one isn't necessarily a bad idea, but it also doesn't bother me that much. I recognize that there may be cases where pardons are morally right but could be politically damaging (e.g. Obama commuting the sentence of Manning...) and thus allowing a president to issue a pardon in the 'lame duck' part of their presidency may sometimes
be a good thing.
The caveat is that there are additional safeguards (such as your 'no self pardons', or as another poster suggested, some way for the senate to challenge pardons).
