Many posts use the word 'dedicated', and come with the complaint that FDev are ignoring explorers because they haven't provided such a ship.
This is, IMHO, different from requesting more ships that can be used by explorers.
In general, it seems to equate to a ship having a good jump range and lots of internals - which is not a configuration that we have a particular shortage of at this point.
The claim of a minimum of 6 internals doesn't stand much scrutiny - my AspX works perfectly well with ADS, DDS, SRV, Shield and Fuel Scoop and depending on what I'm doing I don't always need the SRV or even the shield.
Given that explorers don't even agree about whether long jump range and/or large fuel scoops are necessary, I'm not sure exactly what FDev are expected to provide in a 'dedicated' explorer anyway
