Attaching a picture to an email is not, in and of itself, «some divergent purpose». However, neither is it «fundamental», nor has it ever been.
Back in the early ‘80s, all we had was plain-text (text/plain) emails, and attached files always had to be handled separately.
In those days, attached pictures, to an email, were more analogous to photographs enclosed within the same envelope as a typed or handwritten letter: the receiver had to, sort of, integrate them in their own mind.
Then, in the latter ‘80s, as we were having access to word processing—wherein we could integrate formatted text and images, at least, there was a push for similar capabilities within emails. After all, we now had that capability in “snail”-mail.
So, a number of rich-text formats came into being. The main one that is in most use, these days, is the one based upon the same HTML standard as webpages, text/html.
This used and still uses the same old email attachment methodology used in the early ‘80s, but references the attached files within the body-text of the email to integrate formatted text with images, and other multimedia files, in a manner like unto webpages, to provide a “word processed” email document.
So. The intended purpose of email continues to be facilitating human-to-human electronic communications.
Any attachment (or otherwise) of pictures, or other files, is strictly to facilitate that purpose: in this case, in a manner like unto word processing.
Hence, the attachment of pictures/images/etc. is incidental to the fundamental purpose—not, in any way, «fundamental», in and of itself.
Hence, using email as a means of transferring pictures, and other files, is, fundamentally, «some divergent purpose», compared to the fundamental purpose of email.
However, fortunately for y’all, there does not appear to be a “push” to replace the old attachment mechanism for images/pictures/etc., within the International Internet Standards that govern emails.
So, there is no excuse—at this time—for any email clients to prevent their users from performing bulk attachment operations (such as bulk-saves), upon their received emails, regardless how any given email client may choose to format (render) said emails.
Unfortunately, what has hit you, and all other afflicted parties, here, and in other, similar Discussions, is a tiny subset of email clients (only a single email client and its derivatives, so far as anyone within this entire Community has been able to find) that violates the aforementioned principle.
Furthermore, since none of that tiny subset of email clients is within Apple’s control, Apple has no way of correcting the actual problem.
