If this enhancement will not be used often, can it be worked around with a few lines of script?

no

Is there a reason why this should be core and not an add-on in the asset library?

yes

It's by design as "most modern software does not have confirmation on quit anymore" (and I can tell you that yes, most software does not - there is save on quit automatically so you never lose data when you quit)

This is done by design: godotengine/godot#32321

Closing in favor of #6100.
