That's correct.
Something that I noticed with the switch to musl instead of libc is that the prompt doesn't get printed to stdout before the user types their answer, which is super confusing. Adding the line terminator seems to force the buffer to get flushed and printed to the screen. This is a mitigation for that behaviour. I'm not really sure why it happens and whether there's some kind of a bug in the stack, or if the bug was that it worked before.
