LLMs seem to handle dependency upgrades really well. The task is well-specified, there's usually a build/test suite to check correctness of the modifications, and there's often a changelog they can consume too.

ASTs typically discard comments, and that's usually what you want. The only time (AFAICS) that preserving comments is useful is for writing a code formatter. Could you write a formatter in terms of a list of lexemes? A CST is a non-trivial bit of code for one use case.

It's strange how AOT compilers usually have different modes for optimising time or space usage, but JITs rarely have modes like "prefer fast startup". The vast majority of JITs seem to focus on runtime of hot code after warming up.
