I've come across a few in my time, now I always spec 800 wide cabinets after trying to cable servers in a 600 wide too many times.
Also insist on the following layout in floor cabinets when we re-wire sections
Patch panel
Cable management
Switch 48 port
Cable management
Patch panel
And repeat as required
Flood patched with 150mm cables.
Biting the hand that feeds IT
