I have bikepacked tubleless, have a tubeless road bike, cx bike, and two mountain bikes.

I'm a fan, myself, but things can be finicky at times. When I bikepacked, I still took two tubes with me, a small 2oz bottle of sealant, and patches, just so I was covered for emergencies. I would have probably only carried one tube and no sealant if I wasn't tubeless, but I'm always paranoid that the worst case scenario will play out and I'll be stranded somewhere with two flats and only one tube. Still, a few extra ounces of weight trumps having to change a tube in my book. Tubeless has failed on me a couple of times, but I can't even count the number of times it's saved me from having to change a tube.
