What effort ? I’ve started seeing this attitude more and more. We had a thing that took a week to do before. Now it takes a morning. So we refuse to spend half a day polishing it because it’s too annoying.

Once the initial port is done, keeping platforms in sync is fast. Not to mention that a harness that would automate this would be valuable.

I run codex on an old rpi, it eats 190M of ram for what essentially is a telnet client.

You're mistaken if you think it has ever taken a week to port (and support) an application to native primitives.
