personally i like not to much automatic remove things, its hard to be safe on removal
you want removal so make friendly as possibly but personall still you can remove what you dont want...
i have installed Mate, so im bussy on removing gnome dependcies.. i remove mayby some icons of it also.. it remove also whole or part of the Mate-desktop

if i remove Xfce, it removes the Lxdm also, that is not what i want...
think better to have more control in Pamac! if you remove parts..
and if parts needed..., it must give a menu first on my idea

like on up text:
Cant resolve depencies remove this depencies? :
you get a list where you can choose it wat would be a gonner..
then on the second part it comes shows a list what will be removed..,
personal needs more control in Pamac

dont wanna make you angry about it

, its just my idea... to take more control in it..if you dont read the removal you can do worse,
its not that al users this do on this way remove whole Xfce, but you must see as an option,

dont know who others think about it?
