Even then... it's usually built before it's deployed n the server.. the server is still delivering text, css, js, images and images have always been pretty large. So your connection is tied up for a little bit longer... and as content was smaller in the 90's, connections themselves are much faster today... in the 90's you were lucky to be hosting on a T1 or faster and clients on modems. Today, you've likely got between 100mb to 2gb uplink on your home connections, let alone business connections that generally start at 1gb. 600x the bandwidth for the server from a T1
It's possible enough to work from the publication point backwards.
A T1 today put behind relevant caching like CloudFlare could still get a lot done.
Today's home internet speeds between 1gig fibre and up can handle a lot too.
Understanding what's needed, how it could be delivered, constraints can all factor into how to approach structuring, developing and publishing any web application.
