My opinion is converse.

Actually I think _you_ (as a perl maintainer) are shooting yourselves 
into your own foot.

Consider you have another "perl" installed in parallel the official 
vendor perl and want to test a particular application suite with it.

Using env you can simply use your "experimental perl".

Removing it, you will normally have to edit all of your applications' 
scripts, etc. Not necessarily nice!

Sigh, ... the mob rules? To me, this campaign goes much too far.
