No. And, by the way, stop with the markdown README crazyness. README files are supposed to be readable as plain text and hard-wrapped at 80 columns. I have found some "readme.md" monstrosities with github-specific markdown that were unreadable outside the github website. This is akin to presenting your readme file as a flash ainmation.
Stuff like "## Header" isn't any more "crazy" than the ASCII art used in many Readme's of old and on top of that doesn't rely on specific monospace fonts or fixed width. And more advanced stuff like hyperlinks or tables are hard to do "right" in text anyway, since it's basically meta data without an objective "right" or "wrong" way of representing it.
I also truly believe that it's time to finally let go of the 80-columns obsession. It's not 1975 anymore and even the ancient VT100 from 1978 had a 132-column mode. It's just an indefensible relic that held developers hostage for way too long.
Still want 80 columns on your 4k 27" 10bpp HDR monitor? Fine, but don't insist on others bending over backwards just not anger the grey beards on top of Mount Teletype... Text editors are perfectly capable of introducing proper line breaks even at word boundaries if need be.
It's really just become l'art pour l'art to force this arbitrary (by today's [and by today I mean the past 30 years!] standards) restriction on developers with no benefit to readability.
