What problem will that solve?

The other buffers that we inherit from temacs are all frequently-used
ones, so it makes sense to keep them.  A killed buffer isn't useful,
by contrast.

We could perhaps avoid dumping buffers altogether, and instead create
them all at startup, but it will probably also cause complications,
e.g., because the frame we dump must have a window, which must have a
buffer.  I hope that avoiding to dump that one buffer, even if that
requires to add support for this in pdumper.c, will be easier.
