@MrRadar Interesting question... also I was curious how they implemented this feature.
The answer is: it remains "resource free" if you choose it as the primary one while merging, it looses that feature if you choose it as a secondary unit.
It is implemented as a modifier attached to a unit with EFFECT_ADJUST_UNIT_IGNORE_RESOURCE_MAINTENANCE. Pretty neat. JOSE_DE_SUCRE uses the same trick.
