Title: Add configuration option to optionally disable deep_munge

In relation to #13157 I tried to add option to disable deep_munge if developer is willing to do so. Deep munge is enabled by default to protect those who are unaware of risk, while allowing to disable it if advanced parameter parsing is required in given application.
