Overall, nice!
Still, there are two things I want to resolve:

1. consistent naming: some declarations in AA changed their names, and so some of our functions are also changed, but others don't. I do have two suggestions here, it would be nice to consistently use one of them:

• we change everything to align with the new naming
• we change nothing until AA is stable enough and no renaming is expected

2. using of sequences: AFAIU AA almost all the time returns sequences, and in our case we need to handle most of the declarations from those sequences. I believe we should convert them to lists as soon as possible to not stick in a situation that we recreate those sequences on every call. This was the issue which I fixed not so long ago which causes big performance degradation in K2 analysis.

I am trying to do the former to avoid forgotten context.
But renaming everything is quite hard since you should it manually.
For example, I renamed only namedClassOrObjectSymbol to namedClassSymbol since here the name is crucial and scared for me.

My approach is

• rename only important changes;
• after the AA stabilization, we can rename the remains if it makes sense

I believe we should convert them to lists as soon as possible to not stick in a situation that we recreate those sequences on every call.

I agree, it is a good point. Using sequences from AA should be moderated.
I would say - in the end of a single chain.
