Should most DPS be selfish DPS?

I don't think so. You can have jobs provide non-raid damage utility (thus no tax needed and can still be 'selfish DPS') such as mitigation, shields, and Mantra which would still keep them feeling unique and fun. And no, it was actually significant DPS losses to hold too much for burst windows in HW/SB/SHB, you would for some things but definitely not everything. And I think that's fine, too. Ideally, your rotation would even change slightly depending on if your comp had raid damage buffs or not, so not only is your mastery of your job the fight design, but also your comp design.

Thing there is that creates another kind of meta, or makes that utility useless. Speaking as someone who has mained monk in most the savage raids, my healers have more than once forgotten I even have mantra when I ask them when they need it used, and then tell me when I have used it that the amount of increase to healing didn't actually save them from having to use skills. So you'd need to design fights in such a way that these skills are actually more useful than they currently are, which creates it own new meta of having the DPS that provide more healing and mitigation be required. But, if they did that, then jobs that don't have that utility become unviable because the fights won't be able to be cleared with them.

Like if healing checks were so intense to need the kind of defensive utility skills, parties would demand people bring reaper, summoner, monk, dancer, red mage or other jobs that provide those tools, while refusing to bring jobs like samurai or black mage that don't protect the party, especially if all jobs are selfish DPS. Why bring the jobs that offer nothing over the jobs that do? And even then, there will ultimately be a tier list of which is better and those jobs will become meta, while jobs that provide the less valuable defensive tools will be booted out of PF alongside the jobs that have none at all.

This is actually the kind of problem we saw a lot of in Heavensward. I was kicked out of groups more than a few times in PF, and then saw when I looked into the recruitment that after kicking me, they changed the recruitment to exclude monks from joining at all. Friend who played machinist back then had the same thing happening because bard was meta.
