Pretty much; updating say libssl in a "traditional" system running app, or maybe 2-3 dependent apps fixes the bug.
Put all of them in containers and now every single one needs to be rebuilt with the dep fixed and instead of having one team (ops) responsible, you now need to coordinate half of the company to do so. It's not impossible but in general much more complex, despise containers promising "simpler" operations.
...that being said I don't miss playing whack-a-mole game with developers that do not know what their apps need to be deployed on production and for some retarded reason tested their app on unstable ubuntu while all of the servers run some flavour of stable linux with a bit older libs...
