I don't use Webpack Aliases. Even common-used like @ for src.
I don't think about import. Moreover, I usually don't even touch them. How? I'm using modern IDE. Apps like JetBrains WebStorm, IntellijI IDEA etc have perfect auto-imports.
Not all IDE and not always works perfect with aliases. For example, known bug with resolving alias in project from Yarn Workspace: youtrack.jetbrains.com/issue/WEB-39641
Agreements. I think, if it's not commonly used alias (like @ for src), the code could be too unobvious, unclear with such aliases... It'd unnecessary agreements.
Today it's an application. Tomorrow we want co make a library from a part of code. Won't aliases make our code less reusable?
Maybe we just need to make project structure simpler, less deep?
