Another issue is that in 64-bit address space precise GC gives no advantage as false pointers have low probability, so precise GC seems to be not worth the effort.
I disagree, in the current state of things there is benefit for 64 bit systems: Currently there are many ways to accidentally allocate without the NO_SCAN flag for data without pointers.
The overhead of scanning this non-pointer data can often be significant enough to warrant hunting for mis-flagged allocations.
