This would be less uniform that it sounds.
Technically a package that overrides *all* dh targets with something
completely different is using dh.
And the result of someone spending several man months on converting
the Debian Haskell scripts to dh might be relatively close to that.
As an example, look at
https://tracker.debian.org/media/packages/h/haskell-sandi/rules-0.4.2-2
You can see by the path that /usr/share/cdbs/1/class/hlibrary.mk
uses CDBS, but if it would use dh instead this wouldn't make
a huge difference here.
As developer you are not usually working directly with low-level
CDBS or dh functionality, what you are using is the higher level
haskell-devscripts functionality built on top of that.
If you ever have to use low-level CDBS or dh functionality directly,
then things can get really messy since you might break what
haskell-devscripts is doing.
DEB_ENABLE_TESTS is an API provided by haskell-devscripts.
