You already did all the work but gotta wait for eternity to have your stuff in upstream? Welcome to the FOSS! =)

Believe me it's still not so long. Once upon time in one python project I've been waiting for several years, and eventually found the authors decided to rewrite the code from scratch dumping all the work done.

So be patient man. Be patient. =)

I see, thanks for your advice.
But what would you do in this situation?

@Avihais12344
I'd use the fork until PR's merged.
Somethig like this:
pip install git+https://github.com/freehck/yamllint.git@my-master
