Comment (by arma):

 My preference would be for padding cells to have a 0 byte payload
 currently, and then we randomize the non payload portions of relay cells
 like we (sometimes) say we do.

 Maybe I'm missing something, but I don't understand why we'd want to do a
 hybrid "8 bytes of 0's and then random after that" model for the non
 payload portions of the relay cells.

 As a concrete example, see proposal 289 for a case where we will want the
 non payload part of the relay data cell to be random (even if it's only
 one byte).
