As everybody else already said, less bandwidth is a good thing for most
people, obfuscation is OK when the source is available elsewhere, and
debug=true is not hard for developers to find.
I'd actually disagree with the assertion that debug=true is easy to
find, particularly for people who aren't active developers. Some
random on the internet who just wants to see what our js looks like
(out of curiosity or whatever) is not going to be able to find
debug=true.
