Very interesting. This explains why functionality is different between each DB2 instance. One flavor of DB2 gets XML support first because they had money in the budget to do so, while other DB2 platforms postpone as they don't have enough budget to add it to their DB2 flavor. Lots of man power required to keep them functionality equivalent. It took DB2 on IBMi awhile to get temporal tables where as the other flavors of DB2 had them for awhile.
With programming budgets stretched thin, I am betting they wish they took the approach back then that Microsoft took with SQL Server 2017 which now runs under Linux using a single code base.
Very similar article, but with the dream goal of single code base achieved:
