I have not run into the situation. Initially it was there because other
faults have it.
Which other faults?
exc_general_protection() and do_trap() both call show_signal(), which then calls printk_ratelimit().

When you asked, I went through it and put out my reasoning.
What does that mean?
I went through my patch and check if ratelimit is necessary, and then describe the finding.

I think it still makes sense to keep it.
Because you have a hunch or you actually have an objective reason why?
For example, if a shell script, in a loop re-starts an app when it exits, and the app is causing control-protection fault. The log messages should be rate limited.
