I just wanted to note that I found your response mostly fair and reasonable, @Argyle King, and felt that any parts I had responses to would be, at best, nit picking. 
To make it clear, I think the "learning how the parts fit together before discarding them" necessity is far from limited to GURPS; my first experience with that sort of thing was over 40 years ago, and was with RuneQuest. My only point is that if you find some of GURPS rules too much, either you may be intimidated by not being sure you understand the implications of changing them (if you have a sensible view that most systems have mechanics that interlock to some degree), or alternatively don't have sensible view, fiddle with a part you don't understand, break something, and get discouraged. And to make it clear again, not the only complex game system with this potential problem; I suspect people trying to thin out the Hero System without thoroughly understanding it would be in for, well, some bad experiences.
