In particular an unclean shutdown results in the entire cache being marked dirty on next boot and a lengthy write out of the entire cache begins. This occurs regardless of the mode (writethrough or writeback). This behaviour has been raised previously on upstream linux-lvm and dm-devel mailing lists, but the situation has not changed since at least 2014. I don't expect the implementation to be changed therfor, only that the documentation be updated to highlight this behaviour.
