That solution is a logical selector.  I am talking about jquery that will only
be loaded for specific pages.  If you look at ANY page source in Koha, you will
always see ALL of your jQuery, not just jQuery that relates to that page.

Some libraries have a lot of jQuery, and an enhancement of this nature would A)
reduce the amount of code that is looked at and processed when the page is
loaded, and B) reduce unexpected side effects of jQuery that might affect
unintended pages due to mistakes in the Koha or jQuery code.
