In terms of possible, the answer is yes. In terms of desirable, the answer is no. First, the hack you refer to is not guaranteed safe and should be avoided when alternative meth odds exist. This guideline change is such an alternative that simply adds a single upstream cli flag to workaround the problem.
Secondly, the current standard is to install most scripting language files in human readable form. The new easy_install default violates that. using the flag restores that.

Directory and file interaction is a hard problem. There's no right thing to do in this case. The many possible things we could do all have one drawback or another in certain cases.
