Make AnalyzerConfigOptions available during PostInitialization in SourceGenerators

[SQL-MisterMagoo]

Would it be possible to make the AnalyzerConfigOptions available to PostInitialization in a SourceGenerator?

It would be useful to be able to allow the end user to configure what sources my SourceGenerator adds in this callback, as they may not want all features.

It is not a big problem, as I can always provide multiple SGs and they can then include whichever ones are relevant, but that makes the process a bit more messy for the end developer.

Hi, are there any plans for this feature? I have the same need. How can I help implement it?

If you decide to add this functionality to IncrementalGeneratorInitializationContext as well, it can help solve the following problems:

#47384
#55518

This is somewhat related to #71546, which is looking to resolve another lack of input ability for PostInit operations.
