Maybe I am confused, but when I look on debian repository I see docbook-xsl
package which likely stems from the "preferred" github repo.
https://packages.debian.org/stretch/docbook-xsl

However the description page does not list epub as its native output format 
and instead lists dbtoepub as suggested dependency (your 4th link) which
is likely the real conversion mechanism(?).

dbtoepub itself is there termed as an alpha-quality implementation 
https://packages.debian.org/stretch/dbtoepub
so I wonder whether we actually have some reasonable conversion mechanism
at hand?
