brent file-roller
is the GNOME archiver project, which is continually updated to depend on their latest tech stack (e.g. GTK4, libadwaita, etc.). This leads to situation like happened a while ago, where it doesn't support drag and drop to or from GTK3-based file managers, or depends on libraries/frameworks that the rest of a more traditional desktop doesn't (theming-issues included).
Previously engrampa
was the choice for such more traditional desktops like MATE and now XFCE, but since MATE has some serious man power troubles and development slowed down (or to a halt), the XFCE edition needs something with continued support, hence the switch to xarchiver
.
If you're fine with file-roller
you are free to continue using it in any case.
