How to always show sidebar as menu panel?

So I love how this works for full-page layouts, offering a generous sidebar menu without breaking the layout:

Unfortunately I realized it also changes the user-menu to always slide-in. That’s not such a good experience. I guess it will get more complicated to de-couple the behavior?

As a side-note, I saw that the user menu panel has the classes:
.user-menu.revamped.menu-panel.slide-in
But the sidebar menu panel only has the classes:
.revamped.menu-panel.slide-in
I think it could be helpful to have a dedicated class .sidebar-menu there as well.
