I do not see a point in complicating the build procedure to avoid
using it.

I'd really understand your and Jeff's concerns if I was proposing some
really complex workaround, but it's just extending & making consistent
the "mv" dance we already use for 1/2 our rules already.

Just to clarify my position: I'm not all that upset about adding more
uses of "mv", as I agree it's not a lot of code (and in general I like
making things atomic). Mostly I was trying to understand your use case,
and whether we could be encouraging a more robust workflow there.

And that's what I was prodding at in the last email: what's the reason
that doing it in a separate workdir doesn't work? I did find your
answers compelling that it takes more disk space, and you have to
compile everything twice (I do use ccache myself, but I agree that "oh,
just install ccache" is not helpful advice in the general case).
