It is indeed important feature. I didn't know that we lost it by switching to
tigervnc until this bug. It's on my list to look into adding it. If you want to
help, patches are welcome. ;-)

It's true, neither old tightvnc neither new tigervnc listen on IPv6. It's not a
bug, it's a (lack of) feature. Quick search shows that there are some patches
for it floating around internet. Once any of them makes it into upstream, then
it will get into opensuse.
