A bit of both? Imagine every time you read the word "actor", it is instead spelled something like "actor:ress", or "actor_ress", or "actor*ress" (because the separator hasn't been standardised).

Personally I'm in favour of it, but I will concede that if it's done enough times throughout the text (as German has way more gendered nouns in common use than English) it does come with the downside of breaking the reading flow.
