If they do not log it, it is not an issue then IMO. But if it is an issue, then its going to be more than GWF that are a problem. Browser shims will be a problem, using cloudflare will be a problem, having a webhost will be a problem, cloud servers will be a problem, jquery will be a problem, so the webfonts are actually the least of the problem.
But to answer your question directly, yes, its possible. Somewhere some time ago I wrote something for 1.7 because of it. It might be in the gitter archives, I am not sure.
