I see that dropping armies outside of t-mode has been disable, without any
discussion or configuration options.  

There isn't even any warning message, that armies can't be beamed out of T. 
In fact, you can still try to beam armies, your ship will just sit there on
the planet saying that armies are getting beamed down, but none will ever
move.

If someone doesn't like people playing out of T, this is hardly a good way to
do it.  Not only is it a controversial gameplay change without any discussion
or consensus, it's a poorly implemented gameplay change.
