For the non-European guys, in case you come here, we have several M Apps with no 'MAHP' published, but 'as directed' by ATC eg EGKK, EGLL
And as previously mentioned some procedures in the US may leave one to consider their
what if options.
As long as radar contact and communications with ATC are maintained this is fine. Though I suppose it might be interesting to know what ATC presume an aircraft will do if they go lost comm and miss the approach.
