Let me repeat it (Kent answered it very precisely):

In order to create a byte-vector-like object that doesn't get moved by
the GC, are there GC implementation strategies that require me to use
a type disjoint from movable byte vectors?

(And the next question would be whether I need to say at allocation
whether the vector shouldn't be moved, or whether it's a settable
property of the vector.)

(Kent says probably not.)
