The explanation which I have not seen discussed here is that this is a secret war, in Russia. Putin called it a "special operation." Use of the term "war" in reference to this action has been banned in Russia. This secret war aspect may have had practical effects on command and control. It is possible that by not declaring this more than a limited special action, Putin's deployment options are actually limited.
