Some books have Epub format for the entirety of books and the user might not want individual pdf chapters.
Zotfile cannot handle multiple pdfs (each for a chapter) for a single entry of book. This causes only the first pdf to be treated as the default attachment and the others to be handled by Zotero (and saved in a separate Zotero location for instance)
In my personal experience, the user might want to download all the chapters themselves and combine the pdfs before attach the combined pdf to the entry.
This might cause exceeding the download rate set for Project Muse because it's not treated as a Zotero translator collection of items, where the user get to specify which to download. A single click will trigger all pdfs to be downloaded.
So I suggest remove the the functionality for book but keep it for collections for Project Muse journals.
I was wondering if the Project Muse translator could stop downloading all pdfs attachments for books automatically.

Several reasons for the change (take this book for example):

If this is Ok, I can create a PR.
