I disagree. Take this example:
https://lwn.net/SubscriberLink/732420/9b9f8f2825f1877f/ The printk()
function in the Linux kernel was documented to print new logs to new
lines unless the KERN_CONT option was passed. In reality it didn't
always started new lines and people expected (maybe even relied on)
this - and when the code was updated to match the documentation, they
were genuinely surprised when their code was broken.
