It will be good and bad.
It will be good, because it will provide a Club with an independent measure of how the course is playing, from hole to hole, season to season and year to year. This can assist with under/over irrigation and drainage issues. As golfers, we have trouble remembering last week, let alone comparisons with last year, or three years ago etc.
It could be bad because of the arms race. A new standard for firmness/pace of fairways might evolve. We have already seen the change to fairway playing characteristics resulting from the new hybrid couch fairway grasses (bermuda) coupled with firm fairways changes. Slopes are more difficult to deal with in these situations than with older couch types that gave up less run.
Hopefully, the measures won't try to compare soft-grass fairways with warm-season couch/bermuda fairway firmness/speed. That would nearly be like comparing tennis court surfaces (clay vs hard-court vs grass). Perhaps they might recognise a wide range of speed outcomes as 'reasonable', with a narrower range on 'firmness'.
