Nah, I think you're mixing things up here.
"Toxic" is just a label you're putting on everything you don't like and you're also putting a ton of implications behind it.
If Stacy wants a feature, and she's the official representative, I need to clarify what that feature means. A manager can't shield me from having to research the technical implications, that's my job.
Also, you can ignore calls all you want, if there is a genuine need to communicate, you need to have that call at some point. That's actually your first point in the list above.
I think you never worked in a role above code grunt. As a senior developer, my job is to do all what I described above. I need to do all the technical legwork a manager can't. I need to write everything down. I need to get feedback from stakeholders. That's nothing a manager can do and that's nothing a junior can do.
I code something like half an hour a day.
You'd have to sweat a lot for that to be a factor. Not that it is irrelevant, but humans can drink distilled water just fine. In fact, there are regions, where bottled water is almost exclusively distilled.
So as long as you don't plan to participate in the Tour de France, you'll be fine.
