SELinux is an official release goal for etch.
However, we're currently far from that. So far, very few developers are actually using SELinux (if any), or even testing it. I won't be doing anything on SELinux for the next 6 weeks at least, more likely 6 months.
So currently I don't see how we can manage this goal, unless more DDs (and of course users; you don't need to be allowed to upload packages) help getting SELinux properly integrated.
(You can run SELinux on etch without having to recompile any software I think, but you'll have to do quite a bit of customizing yourself right now.)
For a coordinated effort to get SELinux into shape for etch, there are Debian SELinux mailing lists, but so far they're basically unused.
[Update: yes, one option is to remove SELinux from the etch release goals. I was in fact rather surprised to see SELinux listed there.]
[Update #2: It was pointed out, that the first occurence of "release goals" in that mail is prefixed by "pet". Don't ask me what the difference between a release goal and a pet release goal is, though. I guess something like being in an official wishlist...]
