Of course, it won't: we load all the DLLs dynamically at run time, we
don't link against their import libraries.  The only exceptions I know
of are (1) GMP, and (2) libgccjit (in the native-comp build).

Did you verify that the DLLs include all of _their_ dependencies?  If
yes, how did you do that?

Is that a bug in the MinGW64 HarfBuzz port, or is that a bug in Emacs?
I'm using a 32-bit Emacs build with HarfBuzz all the time, but it's
HarfBuzz I built myself (it's available from the ezwinports site).

I cannot tell you what to do, but it would be nice to have binaries
that can be run on older Windows versions.  So if the build supports
XP and older Windows, keeping the 32-bit build would be an advantage.

If we believe no one will want the no-deps download, why have it at
all?  If we think someone will want it, I don't think they should be
punished by having BW icons on the tool bar.

Yes, I think so.

Which non-default options of practical importance does that leave out?

I think you should build --with-nativecomp.  People can always
uninstall libgccjit or rename it if they don't want to use native
compilation.

> 5) Why is it "--with-nativecomp", shouldn't it be "--with-native-comp".

Probably, but we didn't yet get to splitting such thin hair in that
branch ;-)
