In https://www.gnu.org/software/emacs/manual/html_node/gnus/Startup-Variables.html#Startup-Variables

gnus-use-backend-marks
    If non-nil, Gnus will store article marks both in the .newsrc.eld file and in the backends. This will slow down group operation some.

But grepping `gnus-use-backend-marks' in gnus codebase shows no reference.
