Will "Performance" (and stability) sometime appear in NetBeans roadmap?

I regularly check if there is something new planned in upcoming releases of NB here  https://netbeans.org/community/releases/roadmap.html. Unfortunately that page does not seem to be updated regularly - for example now I see 8.2.1 is scheduled for mid-December (in two weeks), but there is no information about that release.

Anyway, point of this post is somewhat different - over and over again I strongly hope to see there (in roadmap) in bold at first line something like "We've made significant performance  and stability improvements in A, B and C areas". Really. Currently performance is the major disappointment for me in NetBeans. Of course I'm talking about 'production size project', where I really need IDE, not just Notepad. 

The last use-case which encourage me to write here is described in details in this issue https://netbeans.org/bugzilla/show_bug.cgi?id=269229 - (40 minutes to wait for background scan to complete). 

Before that, being very much disappointed by performance of Release 8.2, I did some self-profiling and see there many issues which cause NB to run 10-100 times slower than possible in correct implementation (of course not everywhere, but in some particularly annoying use-cases). Some of them live for years already. I've reported my findings in bugzilla and during last month got some feedback only for 10-15% of them.  It seems that performance is still not the point of concern here :(

Is the some possibility to raise "performance concerns" in upcoming releases?
