I can´t really give any good recommendations, it´s just damn hard to code reliable (and well-performing) checks considering the increasing complexity of our skinning engine, or, in this case, the use of add-ons which modifiy / create some of the XML files.
Esp. dealing with $PARAM[] make lot of stuff non-trivial sadly, and I am not sure if I will ever be able to check all these 100% somewhen in the future.
I will see what I can do in terms of improving them further, thx for feedback.
