Hi Stephen, no isn’t exactly that. I mean to target scripts.
I use Chosen for my admin forms, is a very very popular script, used by many.
Personally I try to write the most clean and targeted code possible. Then if I customize that script (eg. it must be 200px wide on my forms), it will be affected ONLY in my forms.
While there’s plenty of plugins and themes (even by very popular authors) creating code that is affecting also others. I my case, I had this Chosen script interface totally ruined by that theme.
You can’t imagine how many tickets I receive because of this: great time loss for me and unhappy customers.
