Agreed.

Yes - I can write code that will return whether the current executable is built
with the hardened runtime -or- sandboxed. I will do so and add it here as an
attachment. (I'll get it done as soon as I can, but it will probably take a
couple of days to fit in with my work schedule.)
Note that when targeting macOS this will require you to link against a couple
of system frameworks, so it will be necessary to change the build configuration
scripts to take that into account. (I don't know how to do that, but I assume
someone does :-) and I can tell you what option flags to add to clang.)
