That is a diminishing burden as aids are phased out.
Another interesting anecdote from someone who was recently at the Boeing factory was they would like to see 100% autoland with GLS as SOP from 2020 onwards, presumably with CAT III as standard.
I can't vouch for the credibility of the anecdote, but a quick google search for boeing GLS autoland gives lots of hits, including an
FAA 2014 GBAS progress report. The airports would be desperate to avoiding having to spend the money on a conventional ILS with such a tantalizing possibility so near.
