Yeah, SQL transformation is a power use feature that most users of the jOOQ Open Source Edition don't need. In the meantime there have been 2-3 out of the box transformations added to jOOQ, which rely on this framework, unlike most other emulations which are much simpler.
But as you said, you can implement this emulation manually using a derived table. Or, in your particular case, why not just use ORDER BY .. OFFSET .. FETCH? Is your actual query much more complex?
