Close to none I guess.

The argument being? The state of shared libraries will continue to improve
steadily as it did in the past. -wholeprogram (as described above) will cause
issues once D gets there and the 1% deliberate silent breakage increases.

At the minimum there would have to be a runtime error on loading plugins into a
program compiled with -wholeprogram. And to pick up a suggestion on the forum
by Ola, there could be a mechanism in place to tell the compiler which classes
you need excluded from devirtualization, so you can use -wholeprogram together
with plugins.

I didn't follow the discussion around -allinst so I cannot comment on that.
