No, it's entitlement to think that your time is so much more valuable than other people's. So much so, that you think it's acceptable to waste their time and effort because you're too lazy to add 1 line of text to a README.
How am I wasting their time? Most pull requests are people fixing stuff they needed to work for themselves, then just trying to get it patched upstream. Since they needed to do it anyway, there's hardly any time wasted.
Making pull request for stuff that they didn't need is a waste of everyone's time, and totally on the submitter.
