It does matter. IMHO if he doesn’t care enough to make sure he is on the ballot it gives voters everywhere doubt as to whether or not he is hiding something. This could have have easily been laid to rest with a birth certificate taken to court by his attorney, but his attorney did not even show up to give any kind of an argument.
In any case, this will not help him at all.
If there IS a problem (like there isn’t a suitable BC) then showing up wouldn’t help him in any way. Sometimes ignoring a problem is the best hope for making it go away.
