On-disk format robustness requirements for new filesystems

I have a hard time accepting the "It's unfair to expect better of new contributions than of pre-existing code (paraphrasing here)" argument.

Pre-existing file-system code can be hard to fix because a.) it might necessitate breaking on-disk format, which is usually a no-go, b.) regressions have a real-world impact.

Ensuring a high level of robustness on the get-go before merging rather than trying to fix it afterwards is practically guaranteeing that these issues won't ever get fixed.

TL;DR: I totally agree with Christoph Hellwig.

At its worst, it could mean a lack of new filesystems, because they were all held to unrealistic standards, and the current filesystems all bitrotten out, because it's just expected they aren't robust.

Again, for "That's the only way to get the average quality up", this does not seem to be a viable way to get the average quality of Linux up for most users.
