Why do we have to use a special clock face to get SpO2 readings

Why do we have to use a special clock face to get SpO2 readings on the Versa Lite?

@FaithHopeLove7   The Versa 3/Versa 4 and the Sense/Sense 2 have the SpO2 Tracker app that runs in the background.  This app isn't available for the Versa, Versa 2, and Versa Lite.  Fitbit introduced the SpO2 Tracker app with the Versa 3/Sense.  No explanation was ever given as to why it wasn't added to the older models.

Thank you @LZeeW   It would be nice if Fitbit offered this app for older models because their SpO2 clock face drains the battery, although the SpO2 tracker app might do that too.  Who knows.

@LZeeW I get an SP02 Graph every day in the sleep tile, with both the Versa and Versa 2?

I found this searching 

Note that for Versa, Versa Lite Edition, and Versa 2, SpO2 data is only collected when you use an SpO2 clock face. For Inspire 3, Sense series, Versa 3, and Versa 4, you can install either an SpO2 clock face or the SpO2 app to collect SpO2 data. Charge 4, Charge 5, Charge 6, and Luxe users must have the SpO2 app installed. SpO2 data is tracked automatically on Google Pixel Watch and Google Pixel Watch 2; you don’t need to install a clock face or app.

But I don't have the clockface, yet get a graph every day in the sleep tile below the time spent in zones?

@MarkMM   The EOV graph doesn't show an SpO2 value on the y-axis.  In all honesty, it is a meaningless graph.  Fitbit has several clock faces that will show your SpO2 range while you slept.  Some just show your average SpO2.  The Versa 3/Versa 4/ Sense/Sense 2 have SpO2 available in the Today stats on the device.
