Ordinarily, I would agree. I don't do that with my other GitHub repositories nor at work.
But ghidra-delinker-extension's domain is unusually exacting. Mistakes or shortcuts there will cause undefined behavior of the exotic kind that can be exceedingly difficult to troubleshoot. The only way I've found to keep things from imploding is through unusually exacting quality standards that a drive-by contributor (who usually only cares about a particular ISA/object file combination on a given platform) can't be expected to match.
To be clear, I don't go silent when I receive a PR for this project. In those cases, I do engage with the contributor and give high-level feedback. But my spare time is finite and so is the other person's willingness to jump through all of my hoops.
