Maybe what I should have asked is, exactly what "shell command line
length limitations" were you referring to?

I am aware that Linux limits the argument length.  I tested on my
computer and the limit appears to be 131071 characters.  IMO, any
command script even close to that length ought to be factored out into a
separate file, so I don't see that limit being a problem.

If there's any kind of length limitation with -c (whether from the shell
or the OS), possible alternatives would include running $(SHELL) and
piping the script to its stdin, or writing the script to a temporary
file and running "$(SHELL) TMPFILE".
