Places that were doing C++, but found out that the right GC, and JIT compiler, can achieve good enough performance for their business case.

There is nothing "special GC" about it, the failure is to assume there is only one way to implement GC algorithms, as if there is only one way to implement hash tables, tree re-balancing algorithms, .... and then place all languages into the same bucket.

Then we have the modern times with AI driven code generation, where no one cares how their agents are actually doing the work, with what kinds of resource management approaches.
