Yes, but I don't think their complexity is comparable to, for example,
the Java support of Eclipse which has been continously developed
for many years by a bunch of people. Repeating this effort is
no small feat.

Yet, Emacs cannot provide the same level of language support like
other tools for Java and C++, so it is apparent the language support
part has not enough resources.

Motivation can have multiple forms. For example, my idea was financial
motivation:

http://lists.gnu.org/archive/html/emacs-devel/2012-04/msg00476.html

The idea is to make it possible for people to sponsor specific 
features and there is enough bounty then someone will come and
do it. If people don't want to work on them in their free time,
then users can create a money pool (everyone giving a small
amount) and if enough users donates money then someone can work
on it full time until the feature is implemented.

I agree a native solution would be better, but for Java Eclim provides 
these features right now, while a native solution (if it happens at all)
will provide them next year, or a year after that?

These interface packages should not be complicated. They
just talk to the server and then present the data to an emacs 
frontend (like autocomplete). So if a tool is abandoned then
there is an other tool instead, and only this interface
layer needs to be reimplemented which shouldn't be a lot 
of work.
