Currently, young generation assumes that all the on-heap pointers are compressed, which is currently not the case due to the backing-store pointers in Blink. Fixing collections to have Member<> is not easy, because the inlined collections may have the semantics that backing_pointer_ == inlined_buffer_; where the inlined_buffer_ can be off-heap (e.g. on stack). The CL introduces another type of barrier specifically for uncompressed pointers. The followup is to use that barrier from Blink.
