3. It seems like this would increase the "attack surface" for stray pointers in the host program. Granted, writes to stray pointers are not sqlite's fault, but they're an unfortunately common problem... and mmap makes user bugs more likely to directly corrupt the database on disk. Perceived reliability might drop as a result (I'm not arguing that the risk is worth giving up 2x, just pointing it out as a potential unintended consequence).
This is why OpenLDAP LMDB uses a read-only mmap by default. User bugs get an immediate SEGV, and usually the bug becomes obvious and easy to fix.
