I can confirm that as of this past Monday there were indeed employees of the police department (three, to be exact) working the Steps and blowing whistles at would-be sitters. (They wear fluorescent yellow vests indicating that they're working for the municipal police, but they don't wear police uniforms.) So, yeah, while there were still plenty of people milling about, there was no one sitting on the Spanish Steps. Aside from that, it didn't feel too different to me. There were the same number of them hanging out on the Steps this morning (as well as a sanitation worker sweeping the Spanish Steps).
