So probably is good risk management to not include your GitHub ever when applying.

(and the inverse holds as well: if you do want to be evaluated at least in part based on something, consider putting it on your resume).
Still, I'd be pretty irritated to learn that someone decided not to even talk to me because I included a github link to some toy project that they didn't like.
I do think all hiring processes have a component of arbitrariness, so I don’t think it is necessarily a bad sign that a company quickly dismiss candidates from poorly-maintained GitHub accounts. I would gladly not show my GitHub and try to get the job showing my skills in some other way.
There are other processes where you must never fail. For those you want to minimize risks. If you want a job at X and nowhere else, this is your situation. But that's not very common.
Could go either way.
