I'd assume in these languages you can get away with either not using the name, or going for a neutral form (same as when you don't know who you're speaking to) French has that gendered structure too, with workarounds to manage uncertainty.
That assumption isn't valid. In some languages in order to say anything about anything you have to apply either the masculine or feminine form of the verbs and adjectives, so there's no way around picking one of the two, so if you don't know, you must guess or assume.

In any case, I understand your point about there not being many options for gendered pronouns in some languages, but you're also assuming that there aren't movements to change that.
