Remember this is proposed as an alternative to hardforks, which is also 
a "nuclear option".  Hardforks carry significant risks such as 
permanently splitting Bitcoin into two chains if global consensus is 
never reached.  A (generalized) softfork avoids this problem.

I think this can also be viewed as a generalized softfork if one so 
chooses, e.g.

     NewBlock := OldBlock ++ ExtendedBlock
     f(NewBlock) = OldBlock

I do not think this is a bad idea but is more complex than my proposal, 
e.g. users having to move coins between different tiers of blocks.  
Under my proposal the Bitcoin works more or less the same except with a 
larger limit.
