Not me, that would turn funny quite fast.
Would be interested myself in hearing about the viability of using anbox for the basics pain tasks like whatsapp and bank apps.
Last time i used anbox on Nexus5 the OS integration was practically non existant. Did i get right that anbox has to be "adapted" per device, but OS integration is the same for all devices with same OS?

EDIT, Michał answered your question:
Anbox is working on sailfishos on some devices but the dev working on it kinda stopped doing it
