Well, current master version seems to be a better start for upgrading

Do you think these are needed? You need a wrapper anyway, and you don't
use the build inputs. If all TeX subpackages don't use TeX explicitly,
they are better compatible if we change the TeX implementation and also
they can be easily unpacked in parallel when TeX is being updated
