Holy crap, why?

What were they thinking?

There are many wallets out there, with many faults, but this just looks like someone was playing around with some code and then someone else committed it to the build.

Eliminating the fact that the address should have failed 1st basic validation check, [heck my lame ass programmer just starts with does it start with a "1" or "3" or "bc1" ? before even going past that] why would you ever change or touch the address prefix?
