Yippie, it works! I just needed to run geiser-eval-buffer, bound to C-c
C-b. Now it completes imported identifiers as well, yay! :) Thank you
very much.

Still, a pity/bummer that it completion does not consider record-fields.
E.g. within the (operating-system) record, the completion could know
that I want to specify one of the record-fields, rather than suggesting
arbitrary identifiers. (Maybe it's because Scheme is not a typed
language.) Nevertheless, it's very helpful and nice.
