With its new app icon, the Gallery Go app appears to have omitted the "Go" component of its moniker, as 9to5Google noticed. The app's name has been changed to "Gallery" in version 1.8.8.436428459.
Gallery Go was initially released in 2019 as a 'Lite' Google Photos replacement for devices with less technology. The desire for "Go" equivalents may have dwindled as even low-cost devices catch up in terms of RAM and CPU power. It's also possible that Google's no-frills Gallery app is an attempt to reach a wider audience.
The YouTube Go app was announced earlier this month that it would be withdrawn later this year. For lower-end devices, the normal YouTube app should get changes, including more granular control for low-data users.
