We should avoid wildcards, yes (except for static imports), but the order - we should follow the current recommendation of ignoring the order. The main reason it is adding zero value and costs some time (just like whitespace warnings in jcheck).

I agree that we shouldn't _enforce_ the order (and didn't mean to imply otherwise). I do see some value in having a "soft" recommendation, though, and encouraging IDE users to configure their IDEs with those recommendations. Otherwise, it can be a source of merge conflicts if one IDE sorts it one way, and another IDE sorts it a different way, and two different people are proposing changes to the same file. Maybe unlikely, but it has happened.

So the questions are:
1. Should we have at least a soft recommendation or leave it unspecified?
2. If the answer to 1 is "yes", what should that recommendation be?
