Feature request: Duplicated mapper configuration #922
Description
It would be great if there would be a validation that no mapper configuration is duplicated.
TypeAdapterConfig.GlobalSettings.AllowDuplicatedMapperConfiguration
If the property is set to false an some mapper configuration exists multiple times an exception should be raised when the mapper configuration get's compiled.

Hi @Lure5134. This should be one of the first features of ConfigAnalizer.
You can join the discussion here :
For global configuration, this is already ready to use.
But, as in your proposal, there will be a problem with determining the origin config.
In your case, it depends on code execution, and on the file compilation in analyzer case :)
