This is from one of the packagers:
I'd be more concerned with dependencies in the Java/Maven world. If
anyone was a dependency in there like jdbc-postgresql >= 9, you'll
kill them. (This is not a problem in the Debian version number
namespace because 1:4 > 9, but unless you'd be using 1:4.2.0 in the
Maven world as well...)
And the other
I'm in favor of that. Even I, as a packager, almost fail all the times when I
see "9.4" there.
I think the maven issue is real, which may put Jorge's idea in the lead?
