Yes, for this reason I have generally always been in favor of not changing from the defaults as well. I wonder if on sites like meta where we are using the new automatic translation whether that problem is now less of an issue. The PM will be generated in english but then can be translated if you are viewing the site in a different language.
I just checked with a different automation and see it was not translated. I think we have disabled the translation of PMs. @nat can confirm. If so, maybe a separate setting might be handy to still translate automated PMs.
