At least #Linux 6.6.4 & #toybox 0.8.10 can still pull #floppyfw - level numbers in terms of memory efficiency:
About 12 MB on an idling command line is completely acceptable and propably the lowest I could ever get it...
This is promising for OS/1337...

And if spmeone wants to make something like #floppyfw that should be an option.
