Good job Ian and Denis, but am i wrong thinking this requires, that the
author of the plugin is still in progress or available!? Or who may include
min_/max_version to the code?
A lot of Bazaar-Plugins were touched in 2011, 2012 for the last time :-( So
perhaps the author is not in touch with EP anymore -  although his plugin
would work for years...

In clear words: Who should decide? Thats what i meant with crowd-voting.
This is actual feedback.

The downside to this approach is that plugins should remain compatible
with all releases of EPrints (and certainly within a Version: 3.1; 3.2;
The changes that kill plugins are changes to API calls... and those
shouldn't change within a version (so all function/api calls in 3.3.1
should still work in 3.3.14 - though there may be additional
functionality available within those calls, or via new calls)

I'd be happy with

$self->{min_version} = “>= 3.2”;
$self->{max_version} = “< 3.4”;

Anything else, and all Bazaar plugins automatically go "out of scope" on
every new release, until they are tested against an install of that new
