Concern over deprecated project dependencies

[cwdott]

Just installing a new project with vue init webpack <project> and I'm getting all of the following warnings:

npm WARN deprecated [email protected]: Deprecated. Please use https://github.com/webpack-contrib/mini-css-extract-plugin npm WARN deprecated [email protected]: Browserslist 2 could fail on reading Browserslist >3.0 config used in other tools. npm WARN deprecated [email protected]: Switch to the bfj package for fixes and new features! npm WARN deprecated [email protected]: I wrote this module a very long time ago; you should use something else. npm WARN deprecated [email protected]: Browserslist 2 could fail on reading Browserslist >3.0 config used in other tools. npm WARN deprecated [email protected]: CircularJSON is in maintenance only, flatted is its successor.

Should I concerned about these dependencies being deprecated?
