I don't think my usage of the percent style changes the meaning of
"typically".  Our implementation details are typically, but not
exclusively, global variables in the build stage.

I'll consider it, but perhaps explaining this within the same cookbook
entry might be a better idea.  Regardless of the outcome in Guix Devel,
I don't think that constraining variable names *too* hard is helpful,
