That does seem like a persuasive argument.

    Consider the following use case:  A code block is to be moved out of  
    its context in order to stick it into a separate function. I yank it  
    at its destination, write a "def newfunc():" at the top. But now I  
    have to reindent it. Repeated use of C-c > and C-c < do that job just

Suppose you define C-u TAB to cycle thru the same positions that TAB
would cycle thru.  Would that be a convenient solution?
