You probably want to tell me that adding a few megabytes extra is not going to cost more from the hoster. In most instances this is true. What you forget is that everything has to be configured and maintained. Just ensuring the lib gets deployed to the right place, in the right version, and with the right caching-headers, has cost me hours of my life in some instances. When I let a CDN do it, it was minutes. Those days are over. I don't load static libs any more, so the question doesn't even come up. Except maybe for fonts.
