Why does Aliucord use an old Discord version?

• The new Discord app is React Native while the Discord version that Aliucord uses (126.21) is Kotlin. React Native is very slow compared to Kotlin. RN is a framework for building apps using JavaScript, which is not as performant as Kotlin code. Discord’s React Native version is known to have performance issues, especially on lower-end devices, because the app has been ported from iOS over to Android.
• Everything would need to be rewritten, wasting time, considering how bad the new Discord version is.
• Aliucord developers don’t like to work with the new one. Notice from the AliucordRN repository
• If Aliucord ceases to exist, there wouldn’t be any active clients using the good old Discord version.

warning: Bluecord is also a modded client for the old version of Discord, but the main developer is not a good person, so we don't recommend using it.

• Features from new Discord versions can be backported to the old one, and many already have been. What does backporting mean?
• Modded clients for the new Discord version already exist, such as Kettu/Rain.
