Okay, wouldn't a solution be to use what is ready even if it is no longer supported until we develop a definitive solution?

I would argue against actually adding this to the repository. This project has been dead for a couple years and from what I can tell no one has actually stepped up to maintaining the code base or make a new fingerprint manager application.
Arch Linux seems to be having problems building it lately (see comments) because of it no longer being compatible with fprintd that handles the fingerprint support.

In the meantime you could probably try installing fprintd (sudo eopkg it fprintd) and use the console commands for it. I am trying to figure out how I can get the fingerprint support in gnome settings to work.

I had looked for more but I did not find this topic.
I even opened a topic (https://dev.getsol.us/T8839)
I have a ThinkPad x220 and I need this functionality.
Bus 001 Device 003: ID 147e: 2016 Upek Biometric Touchchip / Touchstrip Fingerprint Sensor
How does development work? How is the addition of this functionality done?

There is already a task for this, see T4881. I recommend searching for open issues before you open a new one.
