Well it did happen, and I got a profuse apology from management after I went and gave them some feedback. For the record, it wasn’t the cleaning lady herself, but her supervisor, who had a list of rooms in his hand to call upon. The man that came to the door said and I quote “you are obligated to give us access to service the room once a day”. The front desk tell me that this is an incorrect interpretation of the new rules (which they admitted they are having trouble implementing), and that he should have instead asked to do a security sweep (which he did not). At any rate, when you have let housekeeping in every day for a week, and only put the sign up for three hours to have a shower and nap in peace, only to have them bang on your door until you answer, it leaves a very bad taste in your mouth.
