none these days don't process untrusted data and "slowed down much" needs to be defined very well and not only by a syntectitc benchmark throwing numbers around - if it is not noticeable by a user it don't exist and security was, is and always will be a compromise between user expierience
in other words: leave me in piece with generic benchmarks and things faster in theory not look at the time for recovery when machines where compromised
i ran all network aware services with my own build-overrides with -fstack-protector-all long before fedora considered -fstack-protector-srtong with *zero* difference for daily workloads as example
these days one simple rule: if you can improve security *than do it*
