Thread:Project:Support desk/Amending commits

I often see revision histories of pages like this https://de.wikipedia.org/w/index.php?title=Liste_der_Stolpersteine_im_Landkreis_und_in_der_Stadt_Gotha&action=history. This happens quite often when a user is preparing the page in his/her namespace and then move it to the to article namespace. Also later user prefer to make several commits for safety reasons. For me such many revisions mostly do not create any benefit for later. Why not allowing the user to amend/merge a current commit with the previous one? This would create a more clean history and would save some space on the harddisks of the server. Due to my wording you maybe saw that i am coming from version control software like git where this is naturally supported and widely used to have clean revision trees.
