Once upon a time, that layout was pretty standard on the web. I feel like there is not a penalty for older sites that don't have the resources to update and move from the 90s/00s.

And something is lost there. Now all our sites are bloated with a shit-ton of Javascript. I turn Javascript off by default and are surprised by how many blank pages I get. (If it's a news site, I use archive.is instead of enabling it). Square Space sites don't load most images without Javascript.
