Putting 5:8 odds on getting a firm answer on this

So the Mormon church has held a position against gambling for longer than any of us have been alive—and this is a radically consistent position against gambling in all of its forms, even for things like charity fundraiser raffles.

What i wonder: Is this position an outgrowth of canonical doctrine, or is this an outgrowth of Mormon cultural norms of somewhat over a century ago? If it’s the former, then i’d like to know the basis for it, since i haven’t been able to find it; if it’s the latter, then does that make it a position that’s subject to change at any point in time, should church leadership opt to do so? (And if not, why not?)

(Also, gambling isn’t part of the temple recommend questions, which makes for an interesting gap in its catalogue of orthopraxy.)

Anyway, just wondering about this particular one, and wondering if anyone out there has any insight on the subject.
