It's more that it feels very ephemeral / tenuous as none of it is in an org chart or official. It is basically what problems management has to solve and what seniors are available at the moment.
I am, officially in title and org chart an IC. In reality 10-20% of my time is IC dev work. 6 months ago it was 50%, 6 months before that it was 0%.
Further it feels like too much of a time split to really get any better at any of the aspects - software dev, tech lead, product, people management of this role.
What does this look like in FAANG?
