There is no obligation to do it of course.

If the hardware cannot handle them, it's a hardware bug. If the hardware
does handle them correctly but the software doesn't, that is a bug in
the bridge driver.

We have a couple of host bridge drivers that register a trap handler
and then look at the bridge registers to determine the exact cause.

Which host bridge driver do you use?
