In general:

1. There should be an easy-to-use API, CLI, library, and data (sqlite db or whatever) to query package metadata efficiently.

2. The mythological purity of rolling releases building against edge versions without dependency constraints or maintaining stable versioning causes problems in the real world(tm). There are many cases where past versions are needed. Example: ffmpeg is buggy as hell and has to be managed very carefully. Another example: binutils, gcc, mpfr, mpc, and toolchain friends have to be built together with compatible versions. Further example: don't compile anything with Clang/LLVM 14+ unless you want all of your code to break because some genius decided to break the world out of ideological perfectionism. macports, Homebrew, nix, and Arch are just some who are guilty of this sin.
