and brr weights, Sergiy, but there is no inherent contradiction in
specifying both, because Stata can use only one at a time. Your
impressions (1) and (2) about minimum requirements are not correct.
The -vce- option is not redundant; it is controlling.* If it is absent
from both -svyset- and -svy: - prefix commands, Stata defaults to
-vce(linearized)-. ..

*The weights can also be invoked through the -svy brr:-- and -svy
jackknife:- commands.
