☝️ 🤓 If by master/slave you mean “A system in which the master node is responsible to do everything a slave does plus coordinate slaves”
and by client/server you mean “A system in which a server is responsible only for coordinating clients”.
I don’t think so, because the first window is not special, it just spawns a server if none is assigned.
On gnome super+left click allows you to move windows, by default.
You can also enable super+right click to resize with gnome tweaks. In my opinion this should be the default.
