Eudokian Stories Example Themes and Charms RAW / House Rule

In RoPF, "Example Story Themes, and Virtues & Flaws" p39 has the Magic Theme with Hermetic Virtue and Flaw examples.

In the same book, Charms rules p104 says "The Virtue cannot be a Hermetic Virtue".

Should an erratum be created for the RAW?

I'm thinking about softening the rule: every Hermetic Virtue/Flaw that could be applied as is (not changing the description but not using the Hermetic part of if it's not essential) in another Realm of Power's magic than the Magic one (or maybe other Magic magic than Hermetic) can be used.

What do you think?
