I asked this question several years ago

I'm repeating it, in a more specific form, in the hope that setup has
progressed to the point where I get a different answer.
There are currently five emacs packages: emacs-common, emacs, emacs-X11,
emacs-w32, and emacs-lucid. The first includes things that are needed
by each of the other four, and those four each include an emacs binary.
The binary in the emacs package is /usr/bin/emacs-nox.exe. The other
packages contain /usr/bin/emacs-X11.exe, and so on.
This way of naming the packages doesn't really reflect the contents of
the emacs package. It also means that anyone who installs emacs gets
emacs-nox.exe, even if they plan to use one of the other three binaries.
I would rather rename the current emacs-common package to emacs and the
current emacs package to emacs-nox. But then the new emacs would have
to have a way of requiring the installation of at least one of
emacs-nox, emacs-X11, emacs-w32, or emacs-lucid. Is there any way to do
this with our current setup machinery?
My idea three years ago was to have the new emacs package require a
"feature" called, for instance, emacs-bin, and then have each of
emacs-nox, emacs-X11, emacs-w32, emacs-lucid "provide" that feature.
This is what Fedora does. Achim didn't think this was feasible without
major changes in setup. Is that still the case? If so, can anyone
think of another way to accomplish what I want?
Hi Ken,
Achim recently restructured gnuplot; I used to install gnuplot,
gnuplot-base now obsoletes that, and that is all I have installed;
alternatives handles the priorities if different packages provide gnuplot:

gnuplot-base
depends2: cygwin, libcairo2, libcerf1, libgd3, libglib2.0_0, liblua5.3,
libpango1.0_0, libreadline7
gnuplot-X11
depends2: cygwin, gnuplot-base, libX11_6, <BASE-DEPENDS2>...
gnuplot-qt5
depends2: cygwin, gnuplot-X11, libQt5Core5, libQt5Gui5, libQt5Svg5,
libgcc1, <BASE-DEPENDS2>... libstdc++6
gnuplot-wx
depends2: cygwin, gnuplot-X11, libgcc1, <BASE-DEPENDS2>... libgtk3_0,
libstdc++6, libwx_baseu3.0_0, libwx_gtk3u3.0_0
