But tell this to Google when they send you warnings/errors for your site not being "mobile-friendly". When Google crawls your site...and the Googlebot says your site is not mobile-friendly...then your website drops in SEO & you lose traffic.

This may not be important to some website owners...but SEO is important to many website admins & owners...and mobile friendliness of a website should not be overlooked.

vB4 (out-of-the-box) is less mobile-friendly than vB5...and thus is a concern to those persons trying to optimize website SEO.

"Mobile-friendly" is for smaller screens with lower resolutions and lower bandwidth devices that take longer to load pages. With new phones having the same or better resolution than desktops and 20GB download / 10GB upload caps and with 5G technology allowing one million connections per square kilometer instead of one hundred thousand (the limit with 4G technology) the entire point of mobile-first development is naught. Mobile devices can easily load and display full desktop resolutions.

Having said that you'll still get people who complain about how hard it is to read desktop layouts on mobile devices because the number of pixels is irrelevant on small screens when comparing 1080P to 4K. The human eye can't tell the difference. Those people will still have to enlarge the screen but it has nothing to do with "mobile-first" development. Making a layout full screen might help but that's not the same thing.
