Very helpful to know that! Zimit[1] also uses warc files as an intermediate step to producing Zim files. You can use these Zim files to read and search websites offline with the excellent app Kiwix[2]. I think 'Kiwix for Android' and the Kiwix PWA support Zim files made with Zimit, with support by the desktop Kiwix application currently work-in-progress.
Other useful information about archiving websites is available from Webrecorder[3].
