Can a technology or a script disable the recruitment of an unit ?

[Goutlard]

Hello,
I would like to find a way to disable the recruitment obsolete units once a certain technological threshold has been obtained.

I do know a way - making the barracks above a certain technological requirement unable to recruit those units.
However, that means barracks that weren't upgraded can still recruit those.

Is it possible to have a technology disable the recruitment of an unit ?
Or, maybe make a script (LUA) to disable an unit if a technology has been researched ?

Thank you

In theory yes with following code:

-Bavaria

    if conditions.ResearchType("military_ordnance_standardization_bavaria", context) then
        scripting.game_interface:add_restricted_unit_record("bavaria_saker")
         scripting.game_interface:add_restricted_unit_record("bavaria_demi_culverin")
         scripting.game_interface:add_restricted_unit_record("bavaria_culverin")
    end

I don't know if it's really working.
