I've tried to get MPTCP support in Chrome (default OFF, with a knob to turn on in GUI) but the reason most often people gave was that there is how to handle support.

Heck. I even tried to add it into git because i was having issues with reliable connectivity with WiFi and 5G (i was in a hotel at that time) while working on a project.

So unless, if there is some reason why people kept giving reasons of not include it. I just do not have a reason to add support for $(name your favorite software)

z/OS has this interesting feature AT-TLS (Application Transparent TLS)-an app requesting a plaintext socket may silently get a TLS socket instead (with the TLS implemented in the OS), based on a policy defined by the system administrator.

Maybe the solution might be something similar… an app asks for a TCP socket, but (if the request matches a policy) it gets an MPTCP socket instead-so you could make apps use MPTCP even if they weren’t compiled to support it.

Maybe you could implement this using LD_PRELOAD/ptrace/eBPF/etc

There are different ways to force an app to use MPTCP, where the most convenient method is 'mptcpize run <cmd>', see: https://www.mptcp.dev/setup.html#force-applications-to-use-m...

But the best is to let the app (and their users) controlling that, with a nice option. With Chrome/Firefox/..., we could enable MPTCP per domain for example.
