Okay yeah I'll admit I misread what you were saying, that said I still disagree.
The Klingon war is still over 20 years away, were not designing a ship for afterwards. We're designing one for now.
No one is trying to make this a ship to send into combat. Our rearlines are not going to be some safe space, we're going to be fighting a cloaked enemy who like to ambush, this ship will be their prime target, especially with a massive visible cargo container.
Giving it neither of thse upgrades makes it a deathtrap. I'd rather have served on a Stingray against the romulans than one of these if it ends up with basic shields and only two phasers.
