Could the public test servers be more public?

I saw this post today and it got me thinking:

Why don't Mythic (and GOA) start using their Public Test Servers a bit more imaginatively?

At the moment the PTS is only used to test the next patch, which is fair enough, but it could be taken further. Use it to try out new things, not things planned for patch 1.x but things that it would just be interesting to see working (or not). Crazy ideas from both Developers and the playing community, things like that thread suggested and much more...

Making all AoE cause friendly fire.
Or remove ALL AoE entirely, heals, damage, debuffs, the lot.
Make Tier 4 full RvR with some of each zones PQs converted to Battle Objectives.
I don't know... whatever interesting thing that could be tried out with minimal effort but still providing something potentially funky.

Of course if Mythic were to do this, the hate brigade would jump on it as them showing a lack of direction or something. Pffft... I think it would show a game developer showing more interest in their players suggestions and being open to creativity.
