I've entered the Penguin-19 bugs that I know of into the mac68k bug 
tracker on sourceforge. I didn't add feature requests, like support for 
the Mac LC II 12 MB RAM configuration, or support for zstd-format 
compressed vmlinux. (Nevermind netbsd support, or device tree support...)

Some of those bugs and missing features apply to EMILE as well. IMHO, what 
EMILE really needs is a MacOS GUI like Penguin. So my advice to 
prospective mac bootloader developers is, add a GUI to EMILE rather than 
try to maintain both packages.

That's easier said than done -- Penguin is a hard act to follow. But, in 
theory, thanks to Retro68, it could be done without resorting to 
proprietary tooling. Both the Linux executables and the MacOS application 
could be built with a modern GCC.

Consider that, without a modern GCC, it will be difficult to re-use the 
available code e.g. for kernel image decompression. Hence, it will be more 
difficult to fix the long standing Penguin bug relating to gzip 
decompression (which does not affect EMILE).
