it also removes your configuration; its okay if you want to configure from
scratch each and every time.

Not required. You do it first time, not subsequently. Unless you do make
distclean.

I've never heard one say you need to either. Did you not read that I said
before you have to do the whole configuration from scratch after deleting your
.config?
