The problem is there aren't many XW-30 updated ACEA 'A3' formulations in US
I've google for VOA/UOA on the oils below.
Let me know if you know any.
New 'SP' detergent formulation (Calcium PPM <1800 ):
Mobil1 5W-30 FS
Old detergent formulation:
BMW TwinPower Turbo 5W-30 LL-01
Castrol EDGE Euro 0W-30 A3/B4 --> I like this oil a lot. Lot of PAO
Castrol EDGE Euro 5W-30 A3/B4
Pennzoil Euro 5W-30
Pennzoil Euro AV 5W-30
LiquiMoly Special Tec LL SAE 5W-30
Valvoline Euro 5W-30
Motul 8100 X-CESS 5W-30
You can clearly see that vanilla ACEA A3 doesn't have any test that counts 'LSPI' events unlike API SP/ACEA A7
Daimler 229.5 does have an LSPI test but the specs are unclear. All the oils above have 229.5 approval

I am not debating which OE has the best approval. I said, I would like to use the best available formulation. A3 + 'SP' compatible detergent.
If you read a lot of STLE/Tribology research, the consensus is clear about calcium being a factor in LSPI.
You are right that ZDDP negates LSPI but only when present in very high quantities (not feasible in PCMO)
