The default layout would be already pre-filled based on the language
choosen
on the previous page.
I fond the current situation satisfying, except that newcommers may not understand that there is the keeyboard layout settings and where they are.
I may be a singularity, but I am regularely confronted to the fact that most (?) users seem to be one-language-only.
I hate the translations in most GUI / Programs (comes back from MS WOrd 3 where "transfer" was translated to "lit-écrit" in French...). So my computer runs in UK-English. However, my keyboard is Swiss-French.
So maybe a choice during the setup, such as "keyboard follows Desktop language - yes/no" could be a solution.
