Let's just guess that the FBI/CIA actually managed to compromise Russian computers to get the information in the indictment. That makes it all far worse since, if anybody ever gets captured and brought to trial, he'll be able to get full discovery of highly sensitive sources and methods. Even absent such a trial, if the information was obtained from Russian sources, the indictment is the near equivalent of somebody blowing the Ultra Secret in WW II to win domestic political points. IOW the indictment is, itself, treason because it gives aid and comfort to the enemy by disclosing vital information. After all, if the Russian government was involved, as alleged, the indictment tells a detailed story from which their counter intelligence people can work backward to see what was compromised and how, so Mueller has just given away some of our crown jewels.

Apart from the very real risks you mentioned, Mueller and Rosenstein's attempts to cover up their own spying on Trump raise new issues in international law. If it really is a crime for uniformed military personnel to gather intelligence data in another nation from their own country, then our own military personnel doing the same thing could become subject to international legal claims regarding what they do.

As of now nations don't indict the uniformed military personnel of other nations for their official actions. That is a very important international legal norm.
