It's great to see so many functions platform - in some ways it shows there's increasing interest, awareness, and adoption. The field is still quite young and there will be a lot of experimentation and exploration.

There's also a difference between deploying rapidly for local development (less is better) and actually running a functions platform at scale. AWS lambda reportedly handles over 2B lambdas a day (this was a year ago).

Not every platform needs that kind of scale, but it does put things in perspectives.
