Maybe it isn't asking a question. But, we have never seen anyone ever call the TD unless there is an actual refusal to announce the range, and it would certainly arrouse suspicion that the commotion was all for partner's benefit.
Perhaps the practical solution would be to never assume they are playing the same range they did the last time we played against them, and routinely request the announcement. I don't believe asking the opps to comply with the rules is the type of question which might be prohibited ---unless done rudely. A quick glance at LHO with eyebrows raised and a smile is usually sufficient to wake him up and get an announcement.
