Tell that to jamming.
Well, I don't have much to say to jamming, so I'll amend my statement to
And it does! Omni or stealth field gets added by cargo regardless of whether that cargo is an aircraft or ground unit attached to an aircraft.
@BlackYps
That is not true, it was explained here
My brother in Christ, I know what I said and I know what I tested. When you put an aircraft with omni in a carrier, the carrier gets omni. When you put an aircraft with a stealth field in a carrier, the carrier gets a stealth field. When you put a transport with an attached unit with either of those intel properties in a carrier, the carrier gets that intel property. (Jamming is an exception to this, as noted above).
There have been many statements to the effect that the behavior people are looking to correct is somehow related to how the engine handles a unit attached to a transport inside a carrier. It is not. I suspect that conclusion arose from the coincidence that the only way to get a stealth field unit inside a carrier in the stock game is via a deceiver attached to a stinger. However, as I demonstrated in the mod I posted, a normal aircraft with a stealth field will exhibit the same behavior as a deceiver + stinger combo when loaded into a carrier, if it has a stealth field defined in its blueprint.
That's the statement. It's true. I ran a test and gathered evidence. You can also run my test, and if you get different results you can tell me mine are bullshit. If you'd like to demonstrate in some other way that there is a relationship between the two I'd be happy to see whatever evidence you've gathered. "Stingers with attached units act funny when they're inside carriers" does not imply that every aspect of that situation is a result of that behavior.
Lastly, given that the explanation you posted is in large part verifiable facts, I'll focus on the conclusion:
it seems a natural conclusion that the unit does not exist at that moment
It's a computer program. The existence or lack thereof of what's ultimately a series of bits recorded in one location or another (and it's recorded somewhere, whether it's inside or outside of a box) is not a rigorous idea, so there's nothing there to contradict what I've repeated above.

(finally)
I think in general my answer is yes, but I don't see how it is relevant.
It's relevant insofar as everyone is trying to figure out what point you were trying to make when you brought it up.
