They will be the first thing to break.
I can't stand the amount of fragile connectors people keep installing on expensive boards. My BladeRF's micro USB 3.0 sheared off.
USB-C is even a bit contentious for me. USB-A with the 3.0 extensions is much more durable.
I wouldn't change things on my account. I certainly understand the density advantage to u.fl connectors. They just grind my gears.
Best of luck with the project. I couldn't find anything on "Granita". Is it called "SnowWings" now?
No, I think your feedback is fair, MMCX connectors are certainly more durable. Maybe the tradeoff there is that they are not as common, so I might need to include adapters as well. I would like to have them on the opposite side of the board, so that we can maybe enclose them with the CNC enclosure which would make it truly pull resistant.
The Granita is technically unreleased, the manufacturer has been making changes to the packaging of the chip as recently as a couple of months ago. It's based on the same silicon as the IceWings: https://arcticsemiconductor.com/icewings/
But fair feedback, noted. I can't move the optional OCXO below the enclosure, as that would be taller than the aluminium block itself and require a slot breaking the RF shielding, but maybe I can move the connectors. I'll try and get creative.
Edit, surface-mount MMCX to the rescue? https://i.imgur.com/1GJhJa6.png
