Could you elaborate on the part about platform teams?
In my experience, it's worked out terribly when a company treats a platform team as a catch-all for any back-end service regardless the business domain. On the other hand, it's seemed to work reasonably well when the team has a narrow (and very clear definition) of which services they own and why.
That said, I've never worked directly within a platform team as an engineer, so maybe it just appears that way as an outsider.
