If Hertzner cared they could sign up for the MS SNDS program and see a list of
all the IPs that were currently blocked.
They do that already (as Hetzner customers can see when registering a Hetzner
IP in SNDS). AFAIK they also monitor IP blacklists for their IP range.
One thing I'm wondering: If deliverability with Hetzner is already bad is
there any chance to deliver anything at all from a OVH/DigitalOcean/AWS ip?
(just to get a sense of how problematic Hetzner is)

From our observations.. depends..
Both OVH and Hetzner provide 'rwhois/SWIP' for parts of their ranges,
and those parts are less problematic. The parts with no 'rwhois' are
problematic.
Digital Ocean/AWS, and for that matter any cloud provider that 'rents'
IP(s) for short time intervals, will be problematic, especially if they
don't bother to SWIP/rwhois that you are allocated those IP(s).
And as more operators get into this space (Azure here in North America)
and many others worldwide..
If you don't have the IP(s) long enough to justify SWIP/rwhois, then
probably don't want email from you ;)
But it comes down to this, if your hosting provider doesn't bother to
monitor the outbound activity, they will likely be a bad place for you
to make a home for legitimate services..
