[ksp2] Any API to get the source of an node (which jar and class is an ksNode from)?

[acejingbo]

In KSP1 i used to use source element to interpret which jar and class a ksNode came from (help us tell which jar and class is used, etc.)

In kotlin analysis, FirSymbol also provided ways like FirClassLikeSymbol<*>.sourceElement and FirCallableSymbol<*>.containerSource to retrieve source element of a symbol, which can tell us which jar and class (from classpath) an symbol came from

However, KSP2 chose to hide KaFirSymbol as internal so I cannot access these APIs. Nor did KSP2 provided any API for source element...
We would pretty much have to do reflection if wanna retrieve source elemnt, or know which jar&class an ksnode came from...

Wish list

Is it possible to make KaFirSymbol public to expose the API? Or provide a way to access the FirSymbol? Or provide an public property/function that direct to FirClassLikeSymbol<*>.sourceElement and FirCallableSymbol<*>.containerSource?
Otherwise, is there any other way to tell which jar and class is an ksNode from?

Thanks!
