I've read about 15 messages on this topic and will try to incorporate 
the relevant areas in my response.

LFS 6.9 is scheduled for September 1st.  See the Roadmap in the wiki.

I really don't have a problem with adding DESTDIR in Chapter 6.  In most 
cases I suspect it would only require a few more cp commands and an 
explanation in the Package Management section.  For BLFS to follow would 
be a much larger effort.

I've looked at this and made some posts about it in 2009.  LSB is a 
'trailing' standard and many new capabilities (e.g. Qt4, KDE4, etc are 
not adequately addressed in LSB.  We already address parts of LSB in 
section iv.  We also mention building non-wide Ncurses libraries.

I am not opposed to reworking the bootscripts to be more consistent with 
LSB and setting things up to build the boot order into the scripts 
instead of the Makefile.  Is this enough to relabel LFS to 7.0 instead 
of 6.x?  Perhaps, but I would lean towards no.

That said, the purpose of LSB is to ensure capabilities are in place for 
proprietary binaries to be dropped in place.  As an open source 
advocate, that is not very important to me.

This pretty much fits into the same category as above.  The only reason 
for lib64 to exist is for those proprietary packages that have not been 
updated for 64-bit operation.

VirtualBox?  A system owned by Oracle?  I don't think I'm interested. 
Besides, there is now a 64-bit version.  Does it use 32-bit libraries?

Wine?  So you can run proprietary WIN applications?  See my comments 
about proprietary binaries.

What does EGlibC offer that is not in glibc?  My understanding is that 
it is for embedded systems which are not a target of LFS.

We already do it in BLFS for /etc/profile.d and programs like apache can 
do it with its configuration file.  The only potential file I see in LFS 
is /etc/  Personally, I think having a bunch of files that 
each add one line (not counting comments) to a configuration file is a 
disadvantage, not an advantage.  Seeing all the lines in one place is 
much easier to understand than in several different files in a different
