Completely agreed. Knowing the limits of one's knowledge and accepting feedback when one is misinformed are important skills. I believe I already do that and I certainly don't plan to stop.

If I have a competent tech lead under me, I wouldn't be pushing for a certain technical way to do things except if the requirement came from some external constraint like the business or another team, and I would accept the limits of technical possibility.

I might share my technical input if it happened to relate to my area of expertise in a way that wasn't otherwise sufficiently present, but I want my team to know their stuff, not to defer to my technical knowledge out of some personal need to be the expert. Also my input != final decision, with respect to technical decisions, if I'm not tech lead on the task.

Even if I had to push for or against something, I'd do my best to defer to my tech lead (i.e. not me) to actually come up with and lead the solution. It's not a manager's place to prevent a tech lead from conducting a discussion on technically how to achieve the goal within the applicable constraints.
