The "focus" is mostly on what it's being executed rather than what it's being ignored though.

"Do this operation and ignore these exceptions if they occur"
"Ignore these exceptions if they occur while doing this operation."

It's still understandable, but while I'm familiar with the semantics of try/except, I wouldn't be sure if e.g. this just ignored those specific exceptions or even their subclasses without checking the doc/code.

This seems a good use case.
