Because you need an interactive repl running to have dynamic completion
for one, and for multiple language projects you don't have access to
C/Fortran etc definitions from the interactive session anyways. So at
least the etags integration should be done properly in the core.

Generally you don't want to clutter completion or location tables with
java symbols from all the projects that you import. %99.99 of those are
useless. In most cases you need clojure and java symbols in current
project. Next level is all core and imported clojure symbols. Then all
java classes/methods.

There is an open issue in CIDER on interactive doc completion where this
was discussed [1]. Bozhidar can comment on this more, but the general
idea is that you want to offer completion candidates in some sort of
stages in order to avoid impairing the usability. I think the same
concern is valid for references (for the prompt case and apropos at
least).
