These are features that have NEVER been pointed out before.
Otto Schade described this behavior in 1943, and he wasn't the first, but his paper is the classic paper referred to in most app notes from the rectifier manufacturers, such as the Motorola Rectifier Handbook. See the first .pdf attachment.
More recently, in 1974, Peter Richman gave another exposition of this behavior. See the second and third attachments.
And, of course, the chart on the second page of the GE spec sheet I posted, titled "Derating for shortened conduction angle" is derived from the fact that the diode current when feeding a capacitor input filter is typically rather narrow pulses. So, apparently they knew about this.
