There is this open PR, and this Bug that show what it would take to make this a site-owner configuration option to let this work.
Please consider allowing this or explain why not to allow it. Site owners can set their own Remember me timeout options if allowing a user access to Patreon content after their subscription has lapsed is a possible reason not to do this.
I've also re-implemented the older PR in this PR so if approved it would be good to merge
