The only bad thing about Ethernet cables is that they’re shaped like a goddamn grappling hook. If I wanna pull an Ethernet cable through my desk, I must understand that every other cable in its path is coming with it.
I always crimp my own, including using slide-on/slide-off hoods. That way I can back the hood off before plugging it into the port, which keeps it easy to disconnect, and I can slide it back on before pulling it through a tight spot.
I've never heard it called foreskin, that's pretty funny, but FYI, the proper term is "boot". And I'm a big fan of no boots in the rack. They are nice for desks and places cables might be rearranged constantly, but in switches and backs of servers they just slow you down.
Not to be that person but ethernet is the specification, the "grappling hook" you are referring to is the connector (Rj45 8p8c). Ethernet has a ton of different connectors in the spec from SFP to DE-9 and even HDMI.
