Many apply conservatism by adjusting the altitude setting to something higher than sea level.

no im not suggesting that. I believe the comment i read was that many rec computers do not have conservative settings. That may be so if the computer is an ancient one. I have not seen one for years that does not have safety/ consevative settings.Are you suggesting there are some modern computers that do NOT allow setting some conservatism?
So unless you find that your computer is giving you ridiculously short NDLs, I would just set it to high conservatism and enjoy the dive...
Deco for Divers really needs an update, as it still mentions Bubble Model and Deep Stops as being good things.
Beyond that I found it easy to understand.

I just pulled the trigger on a Perdix AI and while it was my intention to get one soon, I did it now because I no longer trust my Mares Nemo Wide. I knew the Nemo was conservative, but on my last few dives it has been giving me much shorter NDLs compared to the other divers I was with which were very experienced divers. These divers were hugging the reef more than I (photogragher and searching for lion fish) so had deeper profiles and still I always had to ascend to a shallower depth long before they did because I got within a few mins of my NDL. They are using regular rec computers, I think Suunto. After one 2nd dive, I saw one of the divers looking me because I was so shallow (compared to them). I gave him the 'ok' sign and continued following them from above. After he asked why and said he know it can't be air. I told him I was getting close to deco which surprised him as he was no where near deco at that time.
On a dive last week, it did the same. On the 2nd dive I got to about 4 NDL, so started to get shallower, but it wasn't giving me much 'credit'. At 37ft it was still showing me 4 mins NDL. As I approached 30ft it went to 14mins. Then when I got to 29 it showed 99mins. I decided to stay there a bit then slowly started to descend from 30ft and as I approached 40ft I was back at 2 mins NDL. I just went back up and stayed there watching my buddies on reef for quite a while.
¯\_(ツ)_/¯

there are many more computers not on this list that have conservative settings in them. I have 2 aeris and they have them and are not o n this list. the settings are not necessary lables as gf's but they have low med hi or M0 M1 M2 etc and other names but they are there in every computer i have seen. not saying there are not a lot that do not have them just that these settings are COMMON in rec computers
What is the better approach? Trusting the computer or doing pre-dive planning?
this is the comment you seem to have misinterpreted...
