I'd say the most important thing is that as a pilot you are able to select and maintain a reference point, plus arrive there at the correct speed to enable a touchdown and rollout to a stop inside your planned landing area.
IMHO there's nothing inherently wrong with landing an aircraft further down the runway than the TDZ, if you've done it deliberately after assessing LDA vs. LDR for the conditions. The problems start when people land long because of poor speed control and/or inability to stabilise the approach in terms of aiming point.
I have had "interesting" flights with guys who didn't seem to have any consistent technique for putting the aeroplane down and sort of relied on getting it over the end of the runway at various speeds/heights/attitudes, then accepting whatever happened in terms of touchdown point or runway used. I do wonder whether they got like that over time or whether they were *ever* taught to do it properly...
