Others want to make massive 36-channel recordings with Ardour, run
128-voice synthesiziers with SuperCollider, rock the party with Mixxx,
play Csound5 in realtime, edit midi arrangements with MusE, run a live
webradio stream with icecast2 while OTOH others want to harden their
webserver with port-knock logins or set fierce limits for all users.
Should all these packages fight for who should edit limits.conf and
whose edits will finally survive? 

This is not about if users should learn how to edit limits.conf or
not, this is about playing fair with other pieces of software
installed in a distribution.

If it was only about making editing limits.conf easier, here's a way:
Just run this script as root/under sudo: 

if test -w /etc/security/limits.conf
    read -p "Update /etc/security/limits.conf? [yN]: " DOIT
    if test "$DOIT" = "y"
        echo "@audio   -  nice     -10" >> /etc/security/limits.conf
        echo "@audio   -  rtprio   99" >> /etc/security/limits.conf
        echo "@audio   -  memlock  unlimited" >> /etc/security/limits.conf
        echo "/etc/security/limits.conf updated successfully!"
        echo "You need to logout completely and login again to"
        echo "activate changes."
        echo "Also make sure you're in group \"audio\"."
        echo "Okay, doing nothing"
    echo "/etc/security/limits.conf not writable, giving up"
