Mr Whirlwind,
Phraseology such as "terrain clearance is your own responsibility" is currently not in the civil bible of Air Traffic and should not in general be said. The only time a controller might say that, is because a vector has been given below sector safe altitudes, which currently is a no no. They could of course also be saying it because you may have told them you are IMC, they have told you the sector safe altitude and you elect to fly below it. This is arse covering!
Come the 12th of March!
"taking your own terrain clearance" is going to be said! This is because under a traffic service we are allowed to try and turn you into a hill
. You will be hearing plenty of painfully long winded phraseology about limiting a service
, phraseology explaining what the new services are
. VFR PPL's trying out deconflicting service and being vector around the sky before they hopefully tell you that they can not fly in cloud
Reference "land at your discretion", is usually just for something to say when you land off airfield and call final. The word "Final" comes and naturally we must say something back to you with the word "Land" in it.
