Not sure if this has been cleared up yet on a very recent patch (still a couple behind while I slowly finish a game), but I have an issue with the production availability of units that can be upgraded into a limited quantity late-game unit.
Most of the time, when a limited quantity unit (LQU) is unlocked through the tech tree (or other means), any unit (with essentially unlimited producability) that could upgrade into the LQU drops off the production options list in favor of the LQU. This stays even if I've produced all of the LQUs and would like to go back to producing the lower tier units. I've definitely noticed this with Phalanxes and War Chariots.
It might also be handy to be able to produce otherwise obsolete units, if I desperately need a defender or one last counter-attacker, or if I'm flush with gold and can afford to upgrade my way to higher-tier units. This could either be an city screen option button, or a checkbox on a separate options page.
Again, I'm not a modder, so I throw myself on the mercies of the modders out there.
