Won't using highly focused dependencies increase the amount of dependencies?

Limiting the number of dependencies, but then rewriting them in your own code, will also increase the maintenance burden and compile times

A lot of projects are using dependencies, but are only using a small part of. Or are using them in a single place for a single usecase. Like bringing in formik (npm), but you only have one single form. Or moment, because you want to format a single date.
