Python3-ldb-dev only exists in Xenial - >=Yakkety it got dropped again.
>=Zesty it is a sync again and it never existed in Debian.
This came in via:
ldb (2:1.1.24-1ubuntu3) xenial; urgency=medium
* Build Python3 bindings.

There was no bug linked that explains the reasoning to add one in more Detail.
I followed how this was dropped again.
In zesty it became a sync for the minor fixes being in Debian now.
But the python3 things got dropped in:
ldb (2:1.1.26-1ubuntu3) yakkety; urgency=medium
* Drop python3 packages again. No reverse dependencies, and

While python3-talloc-dev exists in Xenial (and only there) it still has no dependencies at all.
$ reverse-depends --release=xenial python3-ldb-dev
No reverse dependencies found
I'd say we might drop python3-ldb-dev from Xenial as well, but since it is released it will never fully drop - unsure what to do about that. Maybe make it an empty package?
Also Doko might have had very specific reasons to add it we just don't know.
So I subscribe him for his general expertise on what to do as well as his specific expertise on this case and why it was added in the first place.
