Do you need the vtable bug fixed?

Well, there are two steps in this involved. First, the code must get
into the compiler. Then, it can be enabled by default.

It is the first step that shows no progress. I personally would
recommend against enabling it by default. Other than me, nobody has
tested the code at all - which alone is a reason not to enable it
in 2.95.
