Rejecting it for it might be a bit over the top, but I can imagine that minifiying and linting is just a part of your regular development process.

However, minifying is useless if there is bandwidth overhead (read: file:// URLs.)

I'm really sad though that there's even in the JS community people that are promoting micro-optimisations like they do in the PHP world..

Opera could just de-uglify the code (and even automate that). still a non-argument to decline a deployment IMO.
