Why should the applications care? Only GPSD ever *sees* that port - the
applications are decoupled from it.

Note that GPSD will actually notice PPS over RI and CTS as well.
It doesn't care - a transition on any handshake line is treated
as a PPS event, because the onlty thing it ever means from a GPS.
