Well, yes, if you don't have control over the allocator behavior.  On
the other hand, deterministic behavior is the issue, and given a
deterministic allocator you can do dynamic allocation in the real-time
part as well (other issues not being prohibitive).  That's a good
reason to build your own pools, which is why I include one in my
real-time course.

PS: It is all "dynamic".
