It all depends on textbooks. One can explain different features of Lojban in different order depending on the natlang in question.
E.g. I can see the need in explaining {co'i} earlier for Russian speakers than for English speakers so that the first ones find more familiar features sooner.
The same for free word order which in some ways is more limited in English and thus not that relevant.
May be a few more features but these two are most noticeable.
More distant languages might require reworking the order to a larger degree.
