What this means that notifications will work for users not wishing to use play services sandboxed or otherwise.

Most android apps do notifications via FCM, which is Google's, and depends on a Play services implementation. If you ever wonder why app notifications barely work on AOSP distributions without Google services then now you know.

By using an app like Sunup (on Accrescent) you can use Mozilla's notification service via UnifiedPush for apps that use UnifiedPush notifications - such as this one.

Tell your developers to support notifications without Google.

The latest Android version of Keychat now supports message notifications via UnifiedPush.

If you’re using Keychat on GrapheneOS, feel free to upgrade.
