It's to do with the fact that additional parameters are required with GCM and how the tag should be handled. It might be appropriate to handle this by appending it to the output but that adds complications on decrypt in that you don't know in advance where the tag is and would need to buffer tag bytes of data until you hit EOF. None of this is handled by the cipher BIO used by the enc command some additional functionality will be needed for this (and CCM). Steve. -- Dr Stephen N. Henson. OpenSSL project core developer.
