For us techies, no, it doesn't really matter.

For average business owners who buy a WordPress template and some 5€ hosting in order to set up a business card web site on their own, on the other hand, it matters a lot. So if your project targets that group of people then PHP is pretty much the only option; anything more complicated than an FTP upload/MySQL import is pretty much to advanced for them and they generally aren't interested in learning new skills just to get a web site online.

Who's doing that anymore? Either you (or your staff) are technical enough to manage installing a web framework on a server, or you use any of the numerous managed sites instead. (Squarespace, Wix, Webflow, Wordpress.com, Shopify, Facebook, etc)

The last thing a non-techie business owner needs is to worry about setting up a random server with bad PHP code.

There's plenty of businesses selling business card web sites built on WordPress. They usually install it on whatever hosting the customer orders and then leaves the rest up to the customer.

Yes it matters. This is often unessecary maintenance overhead.

A docker container is more overhead than managing your own VPC?
