My uneducated kernel take. Flexibility is acceptable and desirable in small projects or low impact projects.
When the majority of the internet and a good chunk of PC are dependent on your project, predictability and stability is much more important than flexibility.
Reading all the comments (between Kent and Linux), the problem is that the bcachefs dev thinks that his project (the filesystem) is the critically important one and that the Linux kernel needs to bend to his will.
I am a bcachefs user but it is pretty damn obvious to me that the production Linux kernel is more important than an experimental filesystem.
