You could always buy Red Hat Enterprise Linux license, sign up for a support contract, and ask if they could start supporting other operating systems? ("Each branch on this project is intended to work with a specific release of Enterprise Linux").Huh? What would that accomplish?
I think that what Anders tries to underline is that each VDO release is specific to Redhat, and further, is specific to a particular Redhat release. By definition that would complicate potential VDO integration in Debian.

Are you saying that deduplication is not possible with Debian?
I may be mistaken, but I think there is a confusion here about a deduplication at filesystem level and at backup tool level.
At (linux) filesystem level, I think in-line deduplication is only provided by ZFS (and perhaps, out-of-tree, BTRFS)
I do not know precisely your usecase, but if it is to prevent duplication during backup, just use a deduplicating backup tool, it just do that: avoid duplicating backup objects before it could occur. searching for deduplicating software packaged in Debian ('apt search dedup' in a terminal) and sorting backup ones would give you clues.
