The most common Rollup plugins are pretty fast to import (by Node standards), but even those will commonly add on a handful of milliseconds, and it’s not unheard of to have imports literally take seconds. If you don’t need it, why load it? I think that this is a good pattern to recommend.
eslint and stylelint are two good examples of unreasonably slow modules that will commonly be optional. stylelint can take a second or two, and eslint a few hundred milliseconds, because neither of them care enough about startup time. stylelint/stylelint#2454 was me reporting it for stylelint. I wish more people used Rollup on their packages before submitting them to npm.
