Ya, siege tank automatical has researched siege mode and a lurker knows how to burrow, but in both cases they can be disabled using scmdraft 2... I don't know if it can be done in starforge. Heck, you can make a player need to research the archon meld if you wanted to

. I know something similar has been said to this but...
This is not entirely correct. Archon Meld can be disabled, but requiring research is not possible (unless you make a mod).
Giving any unit from 1 player to another indeed gives all the attached upgrade as well, but only if they are enabled for the receiving player. Since the Cloak/Burrow trick only works with the ability researched for the original player, this happens automatically, but you can make it not happen:
First, create the unit for a neutral player who has the ability researched. Then give the unit to another neutral player who has the ability disabled. Then give it to an active player. The active player will no longer receive the upgrade.
As for Siege Mode, if the original player didn't have Siege Mode researched, the receiving player won't receive it either.

IF you create a unit for player 12 and then give it to a human, assuming player 12 doesn't have any upgrades researed, then that unit won't have any upgrades researed.
Yes, but it needs Cloak/Burrow researched in order to do this trick.
