Isn't that exactly what he wants?

I don't think so. See https://mail.gnome.org/archives/libsigc-list/2016-April/msg00011.html.
There's no 'blocked' flag in the signal itself. signal_base::block() won't block slots that are connected after the call to signal_base::block(). signal_base::unblock() unblocks all slots, including those that were blocked when signal_base::block() was called.
