Since The previous version of this question is no longer attracting the attention of any moderators despite my efforts, it's time for a new Tag Renaming and Synonymizing topic.
So let's once more compile a list of tags to be renamed or synonymized to make it easier for the mods.
Below is a community wiki answer to be edited by adding the tags to be renamed and the edit status. The mods can then monitor the post for edits and act accordingly.
I have seeded the lists with the ones that were sitting ignored in the old question, plus a new synonym-in-waiting I spotted that led me to take this action.
