WhatsApp still works on a 9 year old Android I still have. Remember that a large part of the world doesn't have fancy phones, and WhatsApp needs to work on all kinds.
In fact, it's easier to install WhatsApp with severely limited permissions, while I just couldn't install the supposedly much more private Signal without giving it SMS access.
