I find them very useful and they often make the code cleaner. A dynamic run-time bound for a buffer can also make the code safer. VLAs are only dangerous when implemented naively (allocated on the stack without stack probing).

That's how it's implemented in all the major compilers. Anyway, even a hypothetical heap-based implementation would be bad because there's no way to report allocation errors.
