Re: EPUB 3.3 spec conformity issues

Due to the complexity of this specification and number of technologies
used in EPUB publications, EPUB creators are advised to use an EPUB
conformance checker to verify the conformance of their content.

EPUBCheck is the de facto EPUB conformance checker used by the
publishing industry and has been updated with each new version of EPUB.
It is integrated into a number of authoring tools and also available in
alternative interfaces and other languages (for more information, refer
to its Apps and Tools page).

You guys are going against the "de facto EPUB conformance checker" of
the EPUB spec.

I contributed, or was trying to, because I am using texinfo to make a
FREE (as in Freedom) book that will be published on major online stores.

These online stores, need my EPUB file to be in conformance (and they
rightly use EPUBCheck to test for this conformity). If the EPUB file is
not in conformance, it won't be published.

I am not going to waste my time on discussing such a fundamental issue.

I feel bad for others that will be creating non-conformant EPUB files
with `texi2any --epub3`. So I won't be recommending texinfo for making
digital books, anymore.

You are hurting the whole Free Software movement, by rejecting
contributions that make a conformant .texi to EPUB file generation.

Reflect on this action.
