I think you are confusing two kinds of exclusivity: that from real technical challenge which teaches you something (eg how to correctly disassemble a machine) and that from random speedbumps (eg an exotic screwhead).
Have you tried to make a Torx head? I suppose you could get the shape with some kind of mouldable plastic or epoxy, but that's probably not strong enough in practice. They are designed to be set with much higher torque than Philips, hence the name.
