It is true that we offer a high degree of choice to users, but one of
those choices is not which paths to install binaries and libraries
into.
We install some binaries/libraries in /{bin,sbin,lib*} and others in
/usr/{bin,sbin,lib*}; the users don't get to choose which binaries and
libraries go where.

It would, for us, eliminate a lot of customization in the base-system
ebuilds, for example, all of the rearrangement of binaries in coreutils,
splitting of the binaries between / and /usr in procps, all calls to
gen_usr_ldscript in any ebuilds, among other things.
In short, it would make packaging simpler, and maintain backward
compatibility at the same time since the symlinks in / would exist.

Based on what I said above, I don't see what choice is being diminished
by the /usr merge, since we do not give users a choice about how their
file system is laid out, or where packages are installed.
If I'm honestly missing something, enlighten me. :-)
