I'd not put exposure tables in the same class as blind or random reflected measurements. Used properly exposure tables can solve many exposure problems. (Jones and Condit, 1948)And yet they worked and good exposures were made.
Just as with a spot meter, you still have to interpret the data. Some subjects you can walk up to and take precise meter readings of various reflections, while some you cannot.
Are you against Sunny 16?
Exposure tables from film information sheets?
All can be used with good results.
It doesn't JUST have to be one way and wide acceptance light meters have been built for over 60 years for a reason; they work.
