This resonates with me. For my long-running Python projects I usually have a file called small.py which has these, as you put it, micro-abstractions. Over time some stuff from the file gets into the larger projects ... and some stuff doesn't. But I like the comfort of "cognitive offloading" this file affords me: I don't have to keep worrying about increasing the scope of my abstractions.
