Hi Paul, I commented the jira issue and the PR.
I don't see any harm in this approach at meast so it's a +1 from me.

 I am rewaking this rather older subject (see
http://xwiki.475771.n2.nabble.com/XAR-source-projects-should-allow-source-f…
 and older things mentioned there) with yet another attempt which might
 satisfy everyone: an attempt to use XAR-Transformations to include files
 into XARs. It defines two extra transformations:
 - INSERT_TEXT (using an XPath expression): inserts the content of the
 text file
 - INSERT_ATTACHMENT_CONTENT (using a file name): inserts the content of
 a file in base64
 The attempt is detailed in 
https://jira.xwiki.org/browse/XCOMMONS-1614
 and has a pull-request and an example realisation.
 I claim that this attempt allows project developers to nicely edit files
 and let them be combined into a xar when it is the time. See the issue
 for an example realisation.
 I would love your comments.
 Paul
