Delinking by itself isn't a heresy (no more than disassembly or decompilation), but what I do with it definitively is. Ripping out MIPS code from a PlayStation video game and shoving it into a Linux program, dismembering a x86 Linux program and turning it into a native Windows program...

It's when you get creative and throw ABIs out the window in order to create some cursed chimeras that this really becomes heresy.
