But the Pi and the charger would probably still talk on the data lines when
the cable was first inserted, to negotiate the charging voltage and current
that was available from the charger and required by the Pi. The negotiation
may be slightly different since the PSU is actually supplying the current
that the Pi needs to operate, as opposed to charging a battery, so supplied
reduced current (with a longer charging time) would not be an option - it's
all or nothing.
