Please note that that's not necessarily "additional" resource that you
spend.  It's more of something necessary to justify the changes you're
suggesting.  It's true that not all bug fixes / improvements require
explicit demonstration but I'm not very convinced about your analysis
partly because I'm not too familiar with the code path but also
because the code has been stable with years and you seem pretty new to
the area.

Sure, it should be consistent but I'm not sure what you're perceiving
as inconsistent is actually inconsistent.  Anyways, let's please have
something deomnstratable.  We can think more about the interface
niggles afterwards.

Thanks.
