If I’m the PM and the PF asks for a flap setting that generates a warning before the gear is down I just wait until it is showing 3 green then select the requested setting, probably wouldn’t say anything
If I’m PF I try not to request or do anything that would generate a warning, that includes checking we have 3 greens before requesting more than F20 (767)
In 727 days it wasn’t uncommon to request ‘flaps 25 gear down, 30 with the green’ not officially endorsed but we all did it
