Hi Mark!
I need some time to think about all the situations in front of us.
And here's a quick reply to one of your questions:

At least in Artanis server-core (Ragnarok), every blocking I/O
operation from users
(the downstream developer of Artanis) will be scheduled by
delimited-continuations
with suspendable-port. I've made a lot of works to make sure users
don't have to care about
any blocking I/O jobs by themselves, this would be a great selling
point of both Artanis and Guile.
So even if they're trying to load/write very small bytes, the task
continuation will be scheduled by
suspendable-port, and it can not be changed because Guile manages all
asynchronous I/O.
Although this looks unnecessary for small bytes, we can make a fair
scheduler to smooth the situation.
That's why we still need to care for the small bytes I/O.
