(Elves and... rocks? Maybe be being hit by them, but "carefully cultured wooden offgrowths" would be more in line with what they were and are and want to be...)
With magic still in development, I'd be hesitant to suggest that practitioners thereof should be of any particular kind, as doubtless there's already a PlanTM in the works. The alchemy example may or may not be "magic", as well.
For what it's worth, I like the idea of a researching task, where a dwarf can research one of a whole gamut of different things, from better metallurgy (in the more mundane, non-alchemical, way) to new mechanics, and perhaps magic, alchemy, and <foo>omancy of one kind or another... Like "storing item in stockpile" it would be a cover-all name for all kinds of actual subjects being covered, and could be much as the magician suggestion when being applied to the theme of magic (or alchemy... also noting that we already have an "alchemist", albeit more mundane and "chemist-like".)
And/or a "librarian" who needs to maintain books such that any profession can go to the library and (with the right books available, either brought in or made by prior expert visitors) get a bonus to skilling up their animal training skills, or wood-carving skills, or whatever it is that they're doing. (Perhaps an absolute skill-cap on how much you can gain through books alone, but together with more traditional 'immersive' training would be quicker if the necessary materials are available.) Magic users would be as welcome to use (and, as necessary, work towards building up) such a resource, w.r.t. their chosen field.
(I'm now getting visions of a stockpile-like 'library' to which you can set storage of books of specific or general subject types, like "books on alchemy", "books on crafts>woodcrafts, but not any other crafts>*", etc. Set the "books on farming>planting" library zone close to the farming plots for easier and quicker reference by the farmer, while you put the "books on smelting" one down near where you have the magmaforging set-up built for handy reference by those workers... Also books that can be used as entertainment near the meeting area or dining room, but watch out for idle-spirals where most of the fort have their noses in some book or other... Like "It-Was-An-Accident-Honest-Guvnor! On The Minecart Express", "Urist McPotter and the Noble's Bedroom With the Mysterious Lever In It" or "50 Shades of Cyan"...)
