Some useful references about this issue:

https://www.in-ulm.de/~mascheck/various/shebang/#splitting
https://www.freebsd.org/cgi/man.cgi?query=env

Drilling down there shows there was a patch to Linux
proposed in 2004 to split all arguments, but was voted
against by a single person citing compat worries,
but no specific compat issues.
Around the same time BSD changed to processing from splitting
all args to be like Linux for more detailed reasons mentioned in:
https://lists.freebsd.org/pipermail/freebsd-arch/2005-February/003525.html
I.E. the issue of distinguishing args to the interpreter
from args to the script.

Now the FreeBSD env(1) command supports the -S option
to do splitting much as you've proposed, so I see no need to be different.
Could you adjust the patch accordingly?

Also this patch is significant enough that
it would need copyright assignment for inclusion.
Could you start that process?
