So many hackish uses of unix tooling that I'll be able to get rid of from my #Emacs once I'm finally using v29 everywhere.
#SQLite love.
I'm already using #emacsql but it's not quite the same as having it built-in (and I also found out about it after I'd already made a bunch of these unixy hacks...).
Particularly, the built-in support is compatible with non-Emacs SQLite use, while emacsql requires keeping Elisp-readable for everything.
