That logic fails IMO

Too many items? When I decided on a size I'd be willing to carry around, my goal from there on is not to get it as empty as possible, but to get it as _full_ as possible, so long as the basics are covered. Sure, there are quite a few things in my tin that I may not need, that may be considered luxury items. A few fishing parts, some safety pins, and so forth... but so what? Many of these items take up almost no room and just about all of them would be difficult to make a field expedient substitute for if I did find myself in need of them.

Having a kit with tons of items in it does not imply that one is lacking in the knowledge department, nor does having a spartan kit imply someone is skilled enough that he or she does not need anything more.

There is a time when your PSK is packed with too many items: when you're not willing to carry it.
Other than that, more power to you if you can squeeze something else in there that might prove useful, so long as you have the basics covered.
