Afaik, there ECB was and is trying to lower /cap inflation. The logic being that the (pandemic) inflation ( and interest) rate was too high , and to avoid a living cost/ wage spiral.
There will be many more expendirures to come due to, the energy transition, failing international trade, political instability, wars, climate catastrophe, migration, new virus problems, etc. If I were them, I'd up my budget reservation for " unforseen costs " to a 20% to be safe. It doesn't hurt to build some fat before difficult years.
