I find maker-vs-manager a bit brittle as well. A company I'm very familiar with has people going into and out of immersive "modes" that involve creative work as well as communication about that work. So, someone might spend all week in "ABC mode" and have 4-8 meetings about ABC as well as shipping a few features or solutions. Others might advance a few large features and be interrupted by 2-3 meetings, but because they are connected, the immersion is not broken.
