Is anyone up for convincing me that the HTTP accept header is a good idea?
I understand the theory: every resource should have the same URI, and should be able to deliver to clients in the format that they indicate they can best handle - eg an image served as WEBP to supporting clients but falling back to JPEG
But we have 20+ years of real-world experience with it now, and I'm not at all convinced that those theoretical benefits outweigh the drawbacks: mainly its lack of discoverability
