How sure are you that this worked? AFAIK there was no way to
enable/disable an always-on ext. That env var never affected the
extension strings, but only the actual ctx->Extensions struct, which
would indirectly modify the ext string. If the entry in that ext table
was a dummy one, it had logic to not futz with it. (But it did so
silently.)
