Customise Backoffice login screen

Does anyone know if it’s possible to use a custom template for the backoffice login screen, specifically on version 13?

I know you can add CSS/change the image with the instructions here:

But what I’m looking to do is change the DOM.

The only real need I have is to modify the <title> tag in the header, as Umbraco HQ decided to remove the URL from it (presumably for asthetics) and I’d like to put it back.

Edit: This is looking less and less likely, as the code also seems to deliberatly rip out any CSS that isn’t the explicitly documented variables. Meaning if you need to tweak anything else, your code is removed. Not sure why they’ve decided to go so user-hostile with this?

I’ve opened a discussion on the Github project, in the hopes of getting an official answer from UmbracoHQ - Add better support for customising backoffice login screen. · umbraco/Umbraco-CMS · Discussion #15779 · GitHub
