What is the issue with regard to scripting (i.e. pytest scripting) in that the message comes after the prompt? I have tests that depend on the message being printed (which are currently using CONFIG_CAN_SHELL_SCRIPTING_FRIENDLY=y). Also, wouldn't the msgq just run full with this change?

That's actually my problem. I'm using Labgrid with pytest to run CAN commands. My driver parses the console and reads something like:

uart:~$ can send ....
enqueuing CAN frame...
uart:~$ CAN frame X successfully sent

Do you have vt100 commands enabled in our setup?

BTW: I'm also fine with disabling this message in our downstream repo for testing purposes...

You should be able to use a regex for matching this. See e.g. https://github.com/zephyrproject-rtos/zephyr/blob/main/tests/drivers/can/host/pytest/can_shell.py where this is used (and which relies on the message, you are masking out, to appear).
