"Need" might be a bit too strong, but I do want overly obnoxious guardrails not to stand in the way.

Case in point, last week I was poking Opus 5 into writing me some RPi-pico firmware for driving a small e-paper screen. Font was built in right into C code as hex constants. Space being tight, I asked if there is some clever compression that could be applied. Claude thought for good 10 minutes, then guardrail kicked in telling me that was "cyber", and refused to continue.
