I've run into exactly that issue and asked in the Chatterbox where I was given a short explanation and a pointer to this discussion.

I object about "discouraged" being a wise choice. IMO this discourages the not-so-newbies who know about perlpolicy and how to interpret it. If anything, newbies probably give less weight to it (out of sheer ignorance) or (willingly) do not care about potential long-term consequences.

Having been burnt by the given-when deprecation fiasco, I was quite repelled by the mention of "officially discouraged" in threads and now I come to know that this particular formulation is just smoke and mirrors to repel "annoying newbies".

Not good.
