Please no. This book destroys all the identity of the different races and turns them into a generic blob.
False. Tasha's gives you
options for customizing your character's origin. It is not mandated and it doesn't radically change race like you seem to think it does.
From the book:
Everything in this book is optional. Each group, guided by the DM, decides which of these options, if any, to incorporate into a campaign. You can use some, all, or none of them. We encourage you to choose the ones that fit best with your campaign’s story and with your group’s style of play.
