Many Linux kernel developers use at least one or more ext4 file
systems, and they would be very cranky if things became unstable.  As
a result, we are regularly running regression tests to make sure we
don't break ext4 users.

This principle holds true for all open source projects, at those with
responsible developers.  Emacs is constantly adding features --- would
that lead you to be concerned after upgrading to Debian 8 that you
shouldn't use a new release of emacs because it might corrupt your
source files in the course of using it in normal operations, and send
e-mail to the emacs developer's list asking if it's safe to use "the
new emacs"?

P.S.  There was a typo in my previous message.  To be clear, 4.0 is
**NOT** is not a long-term supported kernel.  (My previous e-mail
omitted the "not".)
