While dpkg is fine, I'm not sure apt is in this very case.
(There is something strange and often xserver-xorg-video-* packages
are pulled in in strange ways, which might be because of this
circular dependency).

While I agree that circual dependencies are nothing inherently buggy
and to avoided at all costs, they are still something not done lightly.
Apart from broken tools that may have problems with them, it is simply
confusing for users, so a solution without is almost always better than
one with circular dependencies.
At least the description of xserver-xorg should be changed. It still
says:
| This package depends on the full suite of the server and drivers
| for the X.Org X server, as well as providing a configuration
| infrastructure to manage xorg.conf. It does not provide the actual
| server itself, but removing it is strongly discouraged.
This description screams with every single word "you are able to remove
this package but you do not want to unless in strange situations".
Which is simply not true unless the dependency from xserver-xorg-core
to xserver-xorg is not a bug. (And of course increases the confusion
of our users (and of the developers, reading this description I also
first thought the dependency from xserver-xorg-core to xserver-xorg
was some bug introduced by someone trying to fix some bug without
thinking)).
