Point to what external module and why.
Honestly, the likely answer is simply "no". Why would an external
module ever need to make something executable that isn't read-only
code? That's pretty fundamental. Marking data executable is fairly
questionable these days.
Instead, what might work is to have some higher-level concept that we
actually trust, and that isn't about making data executable, but about
doing something reasonable.
See the difference? Making things executable is not ok, but perhaps a
"alternative runtime code sequence" is ok.
