Even a simple case of loading more than 2-3 pages from a given site over a few weeks could benefit from a dictionary for the HTML content (compressing out all of the common template code).

Just about any e-commerce site will involve a few pages to go through search, product pages and checkout.

Most news sites will likely see at least 2-3 pages loaded by a given user over the span of a few months. Heck, even this site could shave 20-50% for each of the pages a user visits by compressing out the common HTML: https://use-as-dictionary.com/generate/result.php?id=d639194...

Any place you'd justify building a SPA, by definition, could also be a multi-page app with dictionaries.

If you have a site that visitors always bounce immediately and only visit one page in their lifetime then it can't help, but those tend to be a lot less common.

It doesn't have to be a huge site to benefit, it just needs users that regularly visit to show large gains.

As CDNs implement support, the effort involved in supporting it will also drop, likely to the point where it can just be a checkbox to generate and use dictionary-based compression.
