Deallocating stack-allocated objects is completely free. Allocating in a thread-local buffer maybe can be fast as allocating on the stack, but the allocations still increase the frequency with which the gc has to collect garbage.

Not quite - the still reachable objects can be evacuated concurrently, and then the whole buffer is reset with literally zero work (just setting the pointer to the buffer's start).
