Thank you all who voted for this request! We have recently made changes which should allow you to see your Username. On Skype 8 You can see it in Settings > Account & Profile under Skype Name field.
In case you created an account using email or phone number you will see your username as live:emailid or live:uniqueidentifier.
No exact release date is available but we are working on adding support to allow users to customize their user name. I’ll keep you posted as we move closer to release

This is so absolutely ridiculous. I legally changed my name almost 4 years ago and I can't change my Skype name.
