I'd say so-called tubeless-compatible tyres aren't necessary unless you need to buy new tyres. For several years now I've been running Hutchinson Confrérie des 650B tyres tubeless on one bike (Velocity A23 rims) and Grand Bois Lierre tubeless on another (MCFK i25 hookless rims), and although neither model of tyre is rated as tubeless, I've had zero problems.
