This all makes sense, and is in the pipe-line for a long time already.

It is all about reforming the old theory loader (and its batch mode) to 
converge it with the interactive document model that is now seen in the 
Prover IDE.

It will probably take a bit more time to get there, extrapolating from the 
slow progress of the past 4 years.
