It makes complete sense to me that the maintainer of a multi-DB tool would collect a table of features like this. My impression is that SQL Workbench/J does not try to hide differences between database systems. The fact that a cell in the table is red is a heads up that the straightforward way won't necessarily work out of the box. There are notes for some of the cells like "since 3.8.3" and "MariaDB 10.1 supports ...". If you have more specific information, I'm sure the author would be happy to get an email.
