Yeah, I feel this one. We currently have significantly less dev velocity than the velocity at which requirements come in. So, unless something actually is the highest priority *right now*, there's a pretty low chance of it ever being worked on.

And then, yeah, I can be "professional" and say that we'll work on it when we find time for it. That's technically not a lie.
But we both know that it's not going to happen, so it's actually better for the customer to take that reality at face value and find another solution.
