IMHO the ubiquitous use of these features by RR hasnt taken away their uniqueness.
These features were quite common in the first half of the 20th Century, they became unique, because the post WWII knife industry rarely used them (at least on the mass-produced knives) and there are fewer surviving old knives now.
I never liked the match strike nail nicks. The ones on some high priced Bulldog knives chewed up my nails, when I tried them, and were nothing but a source of irritation.
That said, I have to admit, that the RR ones are nicely finished, and they do work without attacking my nails. Even so, if I could choose, I would go with the plain nail nick: it is functional, and it does not distract the eye from the shape of the blade, plus it is easier to clean, especially if you use the blade to cut foodstuff.
Personally, I think bells and whistles like swedges and long pulls do not belong on every knife.
There are some patterns and blade types, which benefit from them, but on others they are not only ugly, but also not very practical.
E.g. almost all stockman knives with swedges would have been better off without them. The swedge improves penetration of less pointy blade tips, like the spear point, but weakens the points of the clip point and the sheepfoot blades.
Also, most long pulls on recently manufactured knives are placed way back on the blades, which makes them difficult to open: clearly the person who designed it, did it on paper or a computer screen, not thinking through the functional aspects. Even on old knives, not every permutation was really useful. A feature, which might be elegant, functional in one pattern and given sizes, might have been useless, unless as a decorative element on blades of another pattern and different sizes. Clearly even then marketing and eye appeal was trumping common sense. 20th Century cutlery companies wanted to make money first of all, making functional knives was just a by-product. If there was a market for bells and whistles, they added it. I think the cornucopia of different patterns offered then was a way to test the market for a few decades and it is not accidental, that most patterns did not survive beyond the 1930s.
Today, most traditional knives with "bells and whistles are bought by folks, who only collect them, and rarely, if ever use them, so for them it does not matter if these are truly functional pocketknives, ore just knife-like objects.
There is a reason, why GEC is successful: it produces limited number of high quality bells and whistles knives, which are not only collectible, but, at lest for the most part, also quite functional. Even so, some of their pull designs are also more of an eye candy, than a truly useful feature to open the knife.
