Is most of the removed code functionality that is now in the crypto library used, Botan? A blog post on the decision to use an external library might be good.

Is most of the removed code functionality that is now in the crypto library used, Botan? A blog post on the decision to use an external library might be good. Is there a reason to think that the library will be better maintained than code with similar functionality in GPG? Great work by the way! Thank you!
