Can SaaS MLMs handle multi-region GDPR?

The cloud-native vendors (CloudMLM, Business MLM, Epixel, Infinite) offer regional deployment options. Self-hosted on the same vendor is the most rigorous compliance posture but also the most expensive to operate. Verify the depth in the demo. Specifically ask: does residency enforce at the database tier or just the application tier (database tier is the procurement-grade answer)? What's the technical workflow for Article 17 right-to-erasure including how the genealogy tree handles deletion (soft-delete with anonymization is the right answer, hard-delete that breaks upline integrity is the wrong answer)? Sub-processor list per region with quarterly updates? Standard contractual clauses for international transfers? Vendors that answer specifically have done the work; vendors that defer to a generic compliance team haven't.
