Recent InDesign change suppresses non-printing layers when exporting to EPUB

Question

I hate it when development teams quiety "fix" features I've come to rely on.
I am using InDesign CC 9.2.
Until a recent update, when I exported a book to EPUB from InDesign, layers which were set to show but not print were included in the export. I relied on this because my documents include a non-printed Table of Contents block on the first page of each piece included in the anthology. This block causes the correct page to be set when generating the TOC (notice that it's on the page facing the title, not the title page itself) and is used to print the correct title on the title page of each story and running headers throughout the body.
(An example document - Click for full size)
Up to at least January 2014, when I exported to EPUB, that visible-but-not-printed block was included in the XHTML output. I could then modify CSS to optimize for e-reader display and the title and author names would appear at the top of each piece. Sometime within the past couple of months, that has changed: layers that are not printed also do not export to EPUB. This wouldn't be so big a problem except that the printed title in the image above also is not output to the EPUB file, because it's a text variable in the underlying master page.
If you like reading and messing with markup, as I do, the next two images illustrate the problem.
(The old output - Click for full size)
The new output:

I have five volumes of the anthology so far (comprising roughly 30 stories each) with a new one coming out every three months. Now that this change has been thrown at me, I need to get it resolved or come up with a good workaround while I only have a couple hundred documents to update, instead of double that a year from now.
Thank you for any help or suggestions you can provide!

Going back through every document to override Master Page objects just to get the elements to export is not a realistic workaround.
The change that suppresses visible but non-printing objects is annoying, but at least it's a documented change in 9.2. The change that suppresses all Master Page elements as well is not documented (or at least not documented in an obvious way) and so to me it's a bug.
Ideally, if these new changes are required by some users, the old behavior could at least become an option: the export to EPUB dialog could add checkboxes for "Include non-printing objects" and/or "Include Master Page elements" so that users like me are not left with no way to continue to use existing functionality.
