Backwards compatible is better than simple.

So you don't need to copy your config to the remote server, like XXH does.

So you can still edit your command when your wifi gets spotty.

is that less or more complicated than the mishmash of oddly designed kernel interfaces we have today (fork. mmap. ptrace....so much of it is a mess)

not only would that clean up the lot, and allow for a very straightforward remote indirection, but would open up all kinds of lovely usages like being able to trivially capture and replay command streams. interposition. general purpose rewrites. a well-defined domain in which to upgrade and downgrade the interface schema. and more things I'm sure I've never thought of.
