Why did Chaosium rename Kabbalah to Summoning?

When Chaosium adapted Nephilim from the French version to the US version, they renamed Kabbalah to Summoning and introduced the Kabbalistic Lore Skill that covers understanding Ka-energies in general. Why do this? IIRC, it was because they felt it was inappropriate to reduce an entire mystic tradition to just the flavor for a summoning system. Practical Kabbalah is an extremely dense mystical tradition and has nothing to do with magical evocation. Most of the summons are drawn from the Good Ministers of the Enochian Ethers recounted by the Aurum Solis, in name if not effect, which have nothing to do with Kabbalah.

I agree with Chaosium’s decision here. Kabbalah makes more sense as a mystical tradition underlying all the Nephilim’s occult sciences, not just one. Since each Sefira is associated with a planet, they can be associated with specific Ka-elements. Each Olam has its own Tree of Life with all ten Sefirot too, so it can represent the Ka-elements within the Ka-elements. "As above, so below," and so on and so forth...

For comparison, Mage: The Awakening's Magical Traditions supplement p38-40 provides a symbolic comparison between its ten magical forms and the Sefirot. In Mage: The Ascension, the ten magical forms are assigned sigils taken from medieval alchemy, as recounted in this post. 

I've reproduced these associations on the table below:

Sefira	Planet	Magic	Alchemy Symbol
Malkut	🜨︎	Matter	Amalgamation (process of)
Yesod	☽	Death	Vinegar??
Hod	☿	Life	To Compose
Netzach	♀	Spirit	Fumes
Tiferet	☉	Space	Amalgam (thing)
Gevurah	♂	Mind	To Dissolve
Chesed	♃	Time	Powder
Daat	♇	The Abyss	Vinegar??
Binah	♄	Fate	To Rot
Chokhmah	♅	Forces	To Boil
Keter	♆	Prime	Essence

Hence, it's easy enough to assign symbolic associations between the Tree of Life with Sorcery and Alchemy. Practical Kabbalah works for Sorcery, while Alchemy and Kabbalah were closely linked in the Middle Ages!
