How pevalent is Equal Cost Multi Path (ECMP) BGP? Is it enabled by default?

I wonder how prevalent is ECMP. Do operators use it when they have equal-cost paths, such as in the case of parallel links: https://www.noction.com/blog/equal-cost-multipath-ecmp

Or it's something that is not enabled by default, e.g. due to operational complexity?
