Unofrtunatelly it's still far from XSLT 1.0 branch in terms of support
of various output formats.

Unfortunatelly it's not that easy. IIRC blind replace will trigger the
following restriction from XSLT 2.0 spec:

"There are restrictions on the use of the xsl:result-document
instruction, designed to ensure that the results are fully
interoperable even when processors optimize the sequence in which
instructions are evaluated. Informally, the restriction is that the
xsl:result-document instruction can only be used while writing a final
result tree, not while writing to a temporary tree or a sequence. This
restriction is defined formally as follows."

There is already modified version of chunker.xsl:

https://lists.oasis-open.org/archives/docbook-apps/201103/msg00123.html

But it doesn't completely smoothly work with some widely used XSLT 1.0
based processors, so code is not yet in the trunk. Maybe it's time to
give it another try, or to see whether xsltproc/Xalan users will cry
too much.
