it's usually coding something more precise in a sort of plausible deniability.

Yep. I'm a director now. This is exactly how it is. A big part of being effective in this role is understanding how direct you can be in a given scenario.

A senior manager on reviewing a proposal asks them to synergize with existing efforts: Your work is redundant you're wasting your time.

Option 1 is how I'd say it to a peer whose org is duplicating effort. You can give your advice, but at the end of the day: not my circus, not my clowns.

Option 2 is a more-direct way of how I'd say it to someone in my own org. I'd rephrase to: "Someone else is already doing this; focus your efforts on something more impactful."
