Apart from having 100 ml of fluid sloshing around, would there be any disadvantage to putting sealant in tubes?
I got a puncture on my tubular (very rare event). I carry a small 2oz bottle of Stan's sealant. I pulled over, removed the valve core with the spoke wrench on my multitool and squirted half the bottle in the tube. 1oz, or 30ml, is enough for a 23mm road tire. Sealed up instantly and it sealed so well that a week later the tire was still at full pressure. Ran it with no issues until it was time to replace the tire.
Even if that didn't work I can swap out my spare tubular in less time than it takes to change a tube.
For clinchers, if I lived in an area with dirty roads I would run tubes with removable cores and either carry a bottle of sealant or just squirt the sealant in them during installation. I have zero interest in tubless tires. My experience with them on my MTB, even just trying to mount them, has turned me against them.
