Well, look in a running Emacs session:

(symbol-plist t) =>
(event-symbol-element-mask (t 0) event-symbol-elements (t) modifier-cache ((0 . 
t)))

(symbol-plist nil) =>
(event-symbol-element-mask (nil 0) event-symbol-elements (nil) modifier-cache 
((0)))

So somebody _is_ tacking properties onto t and nil.
