In the product of the singlehtml builder, you will have the entire document in one single DOM tree. For large documents, even modern browsers on a modern machine will be brought to its knees.

Check out the CPython docs for example: https://adrianvollmer.github.io/Zundler/output/cpython.html

This is a huge document, and having this all rendered naively in one single page will not only be hard to navigate, it will also feel really sluggish if not crash the browser.

Ah, ok, so you want a PDF-like single file but in HTML in a way that's more efficient/scalable than the built-in singlehtml builder. Ok fair enough.

For my use cases, the default multi-file HTML builds are ok, and I just pound out a latex-builder generated PDF for the archives.
