Do you use the PHP manual CHM downloads? Why?

Greetings.

TLDR: Do you use (or have you previously used) the CHM manual downloads? If so, why do you prefer them over other downloadable formats (eg. single page or multi-page HTML)?

(I'll note here that currently all downloadable versions are unavailable - this is being looked into by actual PHP core devs who have the required access)

Context:

I've been investigating some issues with the downloadable versions of the PHP manual. In particular the CHM versions are currently manually built.

Additionally the official tools to build CHM files - Microsoft's HTMLHelp Workshop - are no longer available for download from MS and can't be installed on Windows 11 (the installer errors saying a newer version is already installed). These issues make building the CHM files increasingly difficult.

(I also briefly tried freepascal's chmcmd, but this fails to build a working CHM file)

For those who prefer the CHM files, I'd like to understand why so I can work out if there's other alternatives that could be implemented.
