That’s a good point about build instructions, but hopefully they are encoded via a make file. In reality, I only had to make very minor changes to the experimental code to get it to compile, so I really appreciated maintainers keeping backwards compatibility for the most part. Some of this code was over 10 years old, and it still worked… that was pretty impressive since I mostly work with higher level languages where dependencies can change very significantly between versions, or even be abandoned within a decade.
