As in the Portable Executable file format? There are no tricks used in this article that rely on the specifics of ELF, unlike some more extreme examples [1] that abuse every trick in the book to shave off more bytes from executables.
If anything, PE piggybacks on top of COFF which is a complete mess of a file format. I'm currently writing a standalone library for reading and writing toolchain file formats [2] (to replace some messy bespoke code in my Ghidra extension) and this under-specified, fragmented into multiple dialects, weirdly contorted relic is a pain to deal with.
COFF was a stepping stone from a.out to ELF that should've lasted only a couple of years on Unix systems and somehow it managed to metastasize at a crucial point in time inside multiple software ecosystems, most notably Windows and indirectly .NET and UEFI through PE. Frankly, I'd ask instead why couldn't PE and COFF have lost.
