You're kidding, right?

You can't even do footnotes in HTML. (Oh, but you think you can hack 
those together with <sup> and a few <a>? But then you've created 
*endnotes*. What if you want both?) If this question were actually 
serious, I could give you a list a mile long of practices used in 
typography that cannot be replicated in HTML. And did you know that 
you can actually embed multimedia, with captions and/or descriptions, 
*in* a PDF now? Try *that* in HTML.

Some members of the Working Group fail to understand that 
presentation *is* content.

If you really believe the contrary, can we please just write out your 
wedding invitations on Bristol board in pink crayon?

It's been addressed. A wide variety of PDFs can be made adequately 
accessible to many groups. Time has marched on.

Except for all that text inside them.

>(particularly if the PDF is merely a container for scanned documents),

A fair example.

Why, exactly?
