No, this is a totally valid question that I've had too.
The python portgroup has this problem with its py-foo ports; they serve no
purpose; the user should not install them; the user should install the specific
versioned subport. The python portgroup solves this by making py-foo a stub
port that installs just a readme, and declares a dependency on one of the
subports.
Same with the perl5 portgroup, and the new unified php portgroup, and with
ports like VillainousStyle.
It might be nice if MacPorts could automatically tell the user not to install
undeclared subports. That's the reason why I'm trying to declare every usable
subport, i.e. why I make changes like this:
