Yes, it would seem you're not learning *enough* from this history. New laws are being passed that make it legal (hah!) for intelligence services to hack into computers. I would rather different keys for different purposes be separated, and my master key moved offline. If my signature key gets compromised, at least they can only write emails claiming to be me, not sign fake keys on my behalf.
Plenty of skilled people are already using Certify-only master keys. I certainly want to, but it's awkward because I don't want to keep changing my long-term key. As soon as EdDSA is stable, I am going to generate a new one. Many GPG guides propose this. There is very little cost to the user in doing this automatically.
The case is as I said - clearer architecture, and less likely to make mistakes writing programs to interact with them. As security developers, we are trying to improve best practises. In the future, it should be easy to put your master key offline. So it is better to prepare for that situation now, instead of asking everyone to generate a new key and refresh everyone else's key when the time comes.

Be careful what you wish for. http://lkml.iu.edu//hypermail/linux/kernel/0210.1/1834.html
