Thunar is used to display the icons on the XFCE desktop.  It
depends on gvfs, which is used for accessing remote file systems
and the trash inside Thunar.  gvfs in turn depends on samba44 in
order to access CIFS/SMB shares.

Strictly speaking some of these features might be optional.  But
as far I know pkg currently doesn't have a concept of optional
dependencies.  So it's an all or nothing decision, when building
the packages.
