I've started keeping a list of particularly interesting bugs and patches that I've worked on: https://github.com/Wilfred/interesting-code The time that I once removed *a single closing paren* in Emacs is still my favourite.

The most common selling point I hear for Nix is having a list of all the packages you need. On a traditional Linux distro, I just install things and forget about them. A curated, commented list would certainly be handy when I have a new system.

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.
