Hallelujah, Praise the Lord! There's finally a canonical tag for reader-insert fic on AO3!

From the latest admin post:

During this round of updates, we tested a discussion method which permitted many related canonicals to be canonized at once, instead of each canonical having its own separate discussion period. This allowed us to canonize over 200 additional tags from one discussion.
Consequently, we've canonized many additional tags related to Reader-Insert. All Reader-Insert modifier tags will be subtags of Reader-Insert. The full list is available via tag search.

Let us hope that people start using this so that people who want it can find it, and those who don't want it don't have to deal with it!

They're also changing pregnancy canonical tags, so if you've got fic that deals with pregnancy you might want to check it out and figure out if you want to change how you have tagged it.
