If true, this will need to be  fixed ... Not being able to delete / have deleted  Comments or Message goes against the "Right to be Forgotten"  ( now a Law in Europe or al least some European Countries)  ... Plus some Admins maintain a very "tight ship" in the Comments and systematically delete anything slightly off-topic ... Now.,  @HarukaMurakami  if you are not an Admin of your Wiki, just EDITing your comment to replace it by something like "Please Delete" or "/* Candidate for Deletion */" should do the trick  ...

There is no way  the new UCP will not let Admin/Mods take out offending thread / Messages ... Just think of Spam, Politics and Defacing attacks ... For instance, keeping "porn messages" in a Kids wiki History because "it's part of the History of the page" would the the stupidest move ever ...

@Qoushik If you simply meant the orginal addition & following Edits will show in the "Complete" Archive available on the Special:Statistics then I get it. Also I am not sure an "Undo / Rollback"  leaves a trace in the archives  when done right fromn the  "My Tools | History" ... Anyone knows ? ...  If so "UNDO" should be replacted with "MUTE" or "MASK"  (^)  ...
