To state the obvious, Delta is an open standards format which should be widely supported.
Databricks have also bought into Iceberg and will probably lead with that or unify the two in future.

That aside, I was more pointing out that Delta, particularly via a commercial offering, is a data format biased towards Spark in terms of performance, since it is being developed primarily by Databricks as a part of the spark ecosystem. If you are plan to use Delta regardless of your compute engine, it makes perfect sense as a benchmark. However, for certain circumstances, the performance wins could be (in my case was) worth it to switch data formats.
