The new PDF export is indeed ready for wide testing now, I'm working on it at https://etherpad.wikimedia.org/p/BugTriage-mwlib

As part of this change, we will disable ZIM and EPUB export for the time being. If you're interested in working on ZIM or EPUB support for the new offline content generator, or other export formats, please let us know via the above channels.
This is... extremely sad. I've tried for years to get some volunteers to help with Collection's ePub export (even just by debugging), but it's extremely hard when they have no control on what gets integrated nor on the fate of the feature: they just feel it's not their thing. I watched with frustration people spend time on WSexport (a custom, fragile tool); I guess they were right, and I a fool. One thing however I don't understand. The ePub and ZIM generation causes negligible load, was PediaPress asked whether they'd be able to run that service on another server of their own? Ok, WMF must close Tampa and eventually wants to run export in house; but until there is a replacement, it makes most sense to keep continuity, and we need some default service to include in the extension for third party users.
