It has been all over the news, so it won't sabotage anything. Most elderly people from the south-east of Ukraine wouldn't be able to pronounce it as well as they mostly have a very spotty command of Ukrainian.
Apparently even Russian speaking Ukrainians can usually pronounce it as it's a bread commonly eaten at some Ukrainian holiday (source is some random Reddit comment so take with a grain of salt)
I suppose I must have been wrong about generalising it to "most elderly people", but my Granny who had lived in Donbas for 40 years doesn't know about it.
