I was a bit tricky, I have an 8-core arm64 beast called Moto X Force, it's somewhat close to Nexus 5X, so there are some LineageOS builds around.
KBC Mobile app checks for Safetynet, prints out a warning but works. Kudos to the developers. Bancontact app stops working after checking Safetynet. Whatsapp app can be downloaded from the official website. Telegram is available on F-Droid, Skype can be side-loaded as well.
What else is missing?
