Quest Restriction - Mr. Wetbottom's Secret Book

Amos's quest asks to complete the quest chain "Mr. Wetbottom's Secret Book"
I am a level 80 beginner working through Amos's quests.

This quest is not available to beginners, so I cannot access it, and therefore, I cannot continue through Amos's Trailblazer quests.

Mr. Wetbottom's Secret Book is quest id 2019.
I happen to have access to a maplestory source WZ xml and confirmed the job restrictions:

(Note that this is from a later version of maplestory so Aran job id's are listed, too).


Is it possible to remove this job restriction from the questline, considering there's really no logical reason behind the restriction?
