Many BI / analytics tools don't have great support for Data Lakes, so part of the reason could be supporting those tools (e.g. they still load some of their data to snowflake to power BI / dashboards)
We've solved that issue with Trino. Superset and a lot of other BI tools support connection to it and it's a very cost efficient engine (compared to DWH solutions). Another way to go even cheaper is using Athena, if you're on AWS.
They are several versions behind, support for delta was added just recently. Also consider that with Trino you can build a cache layer on Alluxio, making it really fast (especially on NVMe disks).
