It's interesting but I'm not sure component package means much in this context. For instance, this could be patterned on old ordnance but with updated circuitry and/or capabilities. If the transistor package is still produced why change the fundamental design of the munition? I do some hobby work with electronics, and I use old (but still in production) parts all the time. BJT and FET transistors? Not much has changed in a long time for a lot of those. A 2N3904 is what it is.
