There's a lot of people interested in forming some sort of memory layer around vendored LLM services. I don't think they realize how much impact a single error that disappears from your immediate attention can have on downstream performance. Now think of the accrual of those errors over time and your lack of ability to discern if it was service degradation or a bad prompt or a bad AGENTS.md OR now this "long term memory" or whatever. If this sort of feature will ever be viable, the service providers will offer the best solution only behind their API, optimized for their models and their infrastructure.
