Not really - except you expect DESTDIR in every single page. That would be a
huge effort. But when adding new or changind existing pages we could add it.
The most difficult pack on the way thru my working list was PHP, but also ok.
Lets see what X and KDE brings up. All in all I think it would be nice
enhancement but needs to be discussed on blfs-dev.

I'd prefer such a simple approach. That is easy to understand and has no heavy
impact on what LFS is for: Showing how to build an OS. But readers may get an
idea what could be possible using that technique.
I think the part with additional actions (where you generate the list of
dirs/files) should be differently tagged (<userinput remap="binpackready"> or
so). Such actions are totally optional and everyone may want to do different
things there (as it has not really to do with the installation of the pack
itself) - tar it up could be such an action. The "cp -R /" is now the real
install command what previously the "make install" was, and the "install-info
..." is a post-install requirement. That all may needs to be sepearated
somehow. So it seems to me that there are several different parts which even
could be executed on quite different times:
1a) CMMI to the DESTDIR
1b) Cleanup in DESTDIR like removing usr/share/info/dir if exists
2) Optional actions on DESTDIR like filelists / taring etc.
3a) Pre-install like creating users which may own files
3b) Copy DESTDIR to / (or untar to /)
3c) Post-install like install-info
IMHO separating the 3a, 3b, 3c would be quite essential for script generators
to be able to handle those separartly - maybe something like this:.
