Indeed, but this work can end up being very costly. A lot of knowledge might be built into the old code. Even if everything is well documented and there are comments in the right places, it's still easy to lose something in the rewrite. Then you have to balance the reductions in complexity and excision of features that weren't a great idea, against this risk of costly regressions.

This seems like an overgeneralisation. For Perl, given their strict stance to backwards compatibility, we can just keep it. -- Sean Whitton
