Why doesn't /usr/local fit anymore? It was especailly designed for this kind of setup. It will not fit if you define everything underneath /usr as managed software, but FHS didn't do this in the past and nearly all distributions I know didn't work like this.
This could be an option, but several commercial programs use something like /opt/appname what is also valid FHS style. If you symlink /usr/local you could end up an a mixed /opt/lib, /opt/bin, /opt/appname thing.
FHS is a recommendation, nothing more and nothing less. It should only help to find a common base for all distributions like LSB does. But this also implicate that it won't help if only one distribution change the whole FHS style without having the other distributions involved. So putting all binaries to an already defined location within FHS is one thing, but having several new locations is a complete other story an much harder to realize.

If (1) we mount /usr ro over the network, and (2) we want /usr to be reserved for managed software (for a variety of reasons), then /usr/local really doesn't fit anymore.

Because /opt is the only other current directory that makes sense for locally-compiled programs, I would symlink /usr/local -> /opt.

I understand that the FHS recommends installing to /opt/appname, but there is no enforcement of that. Currently compliance is a matter of local policy.
