This simply isn't supported, as stated.

That's right.  Don't think of activity sharing at a granular level;
instead think of it like a declaration of a public space. A Club is
private, is shared among select individuals, or it's public.  Anyone
"on the list" can get in at any time to see who else is there and
perhaps what games are being played.

You don't need to make a Club private to finish a game. The game's
participants can cease sending game data traffic back and forth to
each other, of course, but they'll both remain within the shared Club,
where they could choose to start another game, or not, until they
choose to leave. As long as someone is in the Club, someone is
potentially looking for a partner to play with, and the activity
should remain shared to allow that.

In a sense, you're building something like most online PC games, in
which there is a "waiting room" of sorts where you linger between
matches.  The waiting room is still a shared public space, which can
exist even if no one is actively playing a game.  This argument makes
even more sense with the addition of ubiquitous activity chat, which
would provide a space for kids to discuss what game they want to play,
for instance.  If the Club was made private at the end of every game,
they'd loose this communication channel.
