Org-mode version 8.3beta (release_8.3beta-584-g3953cb @
/usr/local/share/emacs/site-lisp/org/)
GNU Emacs 25.0.50.1 (i686-pc-linux-gnu, GTK+ Version 3.14.4) of 2014-11-17
Hello. Just noticed that after evaluating a code block with C-c C-c
(org-babel-execute-src-block?) all export backends stored in
'org-export-backends' are loaded---or 'required'---automatically. Once
I commented out my 'org-export-backends' setup those backends weren't
loaded, but the default ones did (ascii html icalendar latex).
Is this the intended behavior? Tried to grep my way through Org's
source files looking for a clue with no success.
Also, is there a way to prevent this from happening? It doesn't seem
extremely necessary to me.

`org-babel-execute-src-block' probably requires "ox.el" or some
back-end, triggering. Back-ends are loaded as soon as "ox.el" is
required.

It doesn't really hurt either.

Nope, no harm has been done. Still curious about it though. IMO,
there's no reference to 'ox.el' in the babel source files so I don't
understand how is this possible.

See line 848 in "org.el" (master branch, if it matters).
Basically, Babel requires an export backend ("ox-latex.el", likely),
which, in turn requires "ox.el". The snippet above does the rest.

Ok, finally sorted it out.
Babel doesn't load ox-* files by itself (except for ob-haskell &
ob-latex). But, in my case, the code block's result is a table. In
consequence Org needs org-table which in turn requires some ox- files
and THEN org.el evaluates (after ox.el) 'org-export-backends'.
Thank you for your patience. Now I can sleep soundly.
