I know what you mean.  I started the "cases" and "induct" methods many 
years ago, but piled up only half of the cumulative features that make it 
now close to intractable.

I still do hope that the normal "convergence principle" of Isabelle 
development can be applied eventually, to re-integrate the forks and 
variations that have emerged in recent years.  This also applies to the 
relatively new "co" versions.
