I can't speak for Ihor, but I didn't read what he said to mean that
_all_ non-file-visiting buffer should be trusted.

IIUC, the idea is to provide a mechanism that allows marking _some_
non-file-visiting buffers as trusted.  This would be useful in *scratch*
and ielm buffers, for example.

Such buffers should still be untrusted.
