Why do Scholar's job quests still require a level 30 Arcanist to start?

I understand that it may be programmatically difficult to fully separate Summoner and Scholar in areas like experience points, so I'm only suggesting a partial change in one particular area: If Scholar has almost nothing exactly in common with Arcanist, in some cases even losing some skills that Arcanist had, can Scholar's job quests at least no longer require a level 30 Arcanist to kick off? One of my friends who only likes to play as healer jobs spent a while leveling Arcanist to unlock a job that really had almost nothing at all do with the prerequisite class, so couldn't Scholar just start via a level 30 job quest that can be commenced as any previous class or job, much like how say Red Mage's first quest can be initially started by anyone as long as they're at least level 50?

I'm not saying that Scholar and Summoner have to be completely isolated from a programmatic standpoint yet, since they could still be tweaked to level up together if that's needed depending on the current state of the game's massive code library, but at the very least, it seems like the job quest's class prerequisite shouldn't be needed anymore.
