78% is not pathetic. All major desktop browser versions support it. It's only a ~4% different prefixed vs not. For where it fails, use flexbox and css as fallbacks. The time I've saved using grid and having to deal with fallbacks far outweighs the thought and effort I'd have to put into the same layout otherwise.
