A web server that is configured to support gzip would help alot more
than minification anyway and provides a much smaller size whether the
files are minified or not. Most web servers and web browsers already
support gzip compression so it is not a problem. also the javascript
files are already aggressively cached so it is not a big problem.

considering that with minified files you would get zero to no
information on the source of a javascript error. I think it is a small
price to pay for error reports; otherwise most error reports would be
"ReferenceError: a is not defined in line 7" where line 7 is the
entire jquery source minified. Having understandable error reports is
worth paying a few extra KB. notice that not all scripts are fetched
at once every page load thus it is at most a few KBs more per request
is not much

I think this is the best course of action for proceeding with the
collection of error reports since we are giving deployers the option
of turning this feature off altogether and provide minified files to
their users if it really came to that.
