Are you looking at an old RANCID version? In 2.3.2 there is only one
list of hashes to modify:

# Main
@commandtable = (
       {'admin show version'           => 'ShowVersion'},
       {'show version'                 => 'ShowVersion'},
       {'write term'                   => 'WriteTerm'},

The actual %commands and @commands variables are automatically built based on

To answer the question: yes, just add
   {'show interfaces status' => "ShowIntStatus"},
to @commandtable.

Correct. The hard part is to figure out how to use ProcessHistory.

AFAIK it's the recommended and only way.

I would also recommend to put the code in a separate patch. That way
it's easier to re-apply it whenever a new upstream is released.
