As an engineer I think I can confirm this. The best work relationships were where it was like that. When it was like that, formally scheduled 1:1s were hardly needed anyway. On the flip-side if you really only talk about the stuff that bothers you - and there's even a push towards that - that's the recipe to make such meetings as unenjoyable and intense as possible. Considering that happens with all team members the effect on the team as a whole cannot be too good. Sometimes also people tend to underestimate the time and effort to successfully solve a certain class of difficult problems. Most people are happy when one major problem gets solved eventually instead of a lot but in a quickfix kind of way.
