Should have also said that it is very unlikely that CFM would recommend a gauge for a particular model, and supply that model fitted with that gauge, if there was any doubt about the suitability of such strings. That would be very bad practice indeed, IMHO.
If you’re not already a member, I would strongly recommend that you join the Unofficial Martin Guitar Forum - membership is free, and there are many expert players, technicians, and luthiers on there, and it’s an excellent resource for reliable information…
