Aside a minor point about documenting ’hidden-packages’ although ’hidden?’ is mentioned in section “9.3 Defining Package Variants“ [1], the main issue is fixed by e1bf3c6b5a06b6dbbe4f5a8692ea638a0ce43511. Moreover, please note the section “8.4 The GCC toolchain” [2] in the manual explaining the confusion.
