Every large enterprise has insurmountable difficult even imagining why customers would want something as bizarre as a "stop loss" on their spending...

... right up until it's their own bottom line that is at risk, and then like magic spending limits become a critical feature.

For example, Azure has no stop-loss feature for paid customers, but it does for the "free" Visual Studio subscriber credits. Because if some random dev with a VS subscription blows through $100K of GPU time due to a missing spending constraint, that's Microsoft's problem, not their own.

It's as simple as that.
