It picks up a bunch of automatic dependencies:

   SONAME: libxfce4ui-2.so.0 <-> libxfce4ui>=4.12.1_2

   SONAME: libgobject-2.0.so.0 <-> glib>=2.68.0_1
   SONAME: libxfce4util.so.7 <-> libxfce4util>=4.12.1_1
   SONAME: libglib-2.0.so.0 <-> glib>=2.68.0_1
   SONAME: libc.so <-> musl>=1.1.24_7

does it actually need xfce4-panel explicitly as well?

Yes, because it requires libxfce4panel to build.
I think we can remove it from depends, but it's a plugin for the xfce4-panel so I'm not sure if there's a way to use without it.

[ericonr]

Having plugins depend on the application they are a plugin for leads to weird dependency chains; I'd rather avoid that.
