Resolution Note:
After further investigation, we have found that the increase is predominantly caused by the localization package dependencies.
The biggest increase comes from Newtonsoft.Json.Linq;
It is causing an increase of around 7-8 mb.
Text mesh pro is causing 500kb~.
Addressables and others are causing 2mb~.
When building on IL2CPP with simple usage. After some research, it appears to be a known fact that Newtosoft grows big in AOT-compilation because of its generic handling.
There is no short-term solution we can do on the Newtonsoft side. We plan to investigate some solutions that could help with that though but can't provide a timeline for it.
