It does not change behavior but it forces the value to be a string, avoiding related problems when performing comparisons on "strict", another option as Richard Purdie suggested would be to import the boolean function from /meta/lib/oe/types.py in OE-Core into a new types module in bitbake, forcing it to get a "good" value that we could then use.

No, that's incorrect. The second argument of getVar is a boolean argument named 'expand', which controls whether you get an expanded or unexpanded value. You're now passing a string in boolean context.
