Christian: I'm not sure what you're arguing for here: Either (a) the
user should always have the *possibility* to change the exchange in the
withdrawal flow or (b) the user should always be *forced* to see the
list of exchanges (where the default is selected) and click "next".

I agree with (a) but not with (b).

But my bigger problem right now is that the big picture is not written
down coherently anywhere.  It makes it rather difficult to discuss and
keep track of what the current consensus is, as well as what the
rationale for getting there was.

I don't want to read Kotlin code or play around with the Android wallet
to know what our idea of the withdrawal flow is.  And having to search
through more than a dozen of emails for this is very painful too, and it
prevents new people from getting up to speed (when, say, we want to hire
a dedicated UX/design person at any point in the future).

Can we please write this down in a new design document in docs.git?
Probably some very informal "state machine" in text form would be a good
way.  Alternatively/additionally, some user-centric stories like we've
done in the Prototype Fund UX coachign.  Better ideas are of course
welcome too ;-)  Belen-style sketches can be included there too.  Better
to have them there than floating around in random e-mails!

Torsten, would you mind starting with this?
