Hi, I wrote the PEP 509 as part of my abandonned "FAT Python" project which was a ahead-of-time optimizer using runtime guards to deoptimize code. I planed to abandon this PEP as well, but the dictionary version was used by LOAD_GLOBAL opcode cache which made the version useful and so the PEP was accepted in Python 3.6.
As soon as LOAD_GLOBAL and LOAD_ATTR optimizations are not lost, I'm perfectly fine with removing the dictionary version. As it was said in other messages, there is now a per-key version which can be used instead, if I understand correctly.
