Not necessarily. Evolution doesn't optimize trait by trait.
If the flight response leads to overall more reproduction it would naturally pass on regardless of any effect of the loss of pouch control.
The dropping of the baby wouldn't necessarily be a trait itself, but a side effect of the flight response.
Evolution doesn't work that way. It's not picking and choosing traits. It's not making analysis.
The quokka just survives to pass on that trait so it persists.
What if their oldest loses their job and can’t find a new one, but has to move back, and then can’t because they downsized to a smaller house?
What if their oldest loses their job and now for no fault of their own the renter is suddenly forced to find a new place to live to accommodate the landlords son? But they've been spending their money on rent so they don't have enough savings to find a decent place?
And now they are taking away the next generations ability to buy and pay for a house by making them fund their retirement.
Why do we have to sacrifice our future ability to retire and own a house because they bought all the houses and retired first?

Adrian Zenz saw it in a dream. Is that not proof enough for you?!
Iron Sheik approves this message.
He can break his back with the camel clutch for eternity now.
History does not make itself unfortunately.
You don't have to sneak in a room to agree not to talk about it if you already agree not to talk about it. You just don't talk about it.
Has she talked about it? If she has you may have a point. Otherwise you are running defense while being objectively wrong.
So I take it you are anti "AI art"?
How do you feel about pirating? I see AI art as pretty much the same.
If the relaxation of the pouch is directly tied to the stress/adrenaline response diverting resources elsewhere, which aids in escape, then it's not so easy to optimize to not loose the pouch. Pouch relaxation wouldn't be the genetic trait being selected for or against, flight response would be.
It can be more harmful for the pouch to be relaxed than not on an isolated level, but if that's counteracted by the increased ability to escape due to resource allocation then it would pass on as a "by product" regardless of its individual effect.
There may not be an existing genetic variation which maintains the pouch control during the flight response without compromise on the degree of speed or intensity dedicated to the escape. Evolution can't select for mutations that don't yet exist in the gene pool.
