I've improved my last patch. Now it can work on versions 34 and 35. I 
also fixed an issue that could prevent me from communicating with a 
server that doesn't have this patch. But I'm not sure if it's gone. I 
don't have any linux devices on which I can run nextcloud for 
experiments. But in any case, it allows nextcloud to work with other 
instances that have this patch. It's better than it being completely 
inoperable
