We're not really bringing updates to this package anymore.

laravel/ui is a good example of stability, and the only auth package that can work without JS. Two important criteria for people with time, knowledge or security constraints (removing a whole language of the equation).

It is also the most used auth package by far (Packagist lists 70k installs/month − 2.5 times more than Breeze, 5 times more than Jetstream).

With such minimal maintenance, does it really make sense to deprecate it ?

@taylorotwell would you mind reconsidering support for this package for a longer period? We have a number of legacy applications that would greatly benefit from extended official support. Please also see @d-damien's points.
