Can you elaborate what scripting and software tools are needed? If you'd talk
about RSVP particularly AutoBW and SR, then yeah, but SR on itself should
be less of a chore than LDP.

SR is what MPLS was intended to be day1, it just wasn't very marketable idea
to sell MPLS and sell need for changing all the IGPs as well.
LDP is added state, added signalling, added complexity with reduced visibility.
SR is like full-mesh LDP (everyone has everyone's label POV), while also
removing one protocol entirely.
