When you have low setup like that it is very particular to the player and strings. When you sell your ukes, the new buyer may ask for a higher setup. Therefore, I don't think it is a good thing for manufacturers to ship with such low setups because it'll severely limit the end customer's choices.
I believe if Kala's actions can trigger its competitors to also include such guarantees with their instrument, then it is a total win for us consumers.
For example, many places that perform setup for instrument purchases and does an intonation check, when I asked about what is acceptable intonation error, I never get a straight answer (please try asking this yourself next time, it is not easy to get an answer before your purchase even when intonation should only improve with a proper setup). But as a buyer, I don't really care about intonation check, I care about what error level rejects an instrument. If all uke manufacturers say something like "our instruments will not give you more than +/-7 cents error at 12th", that's go a long way.
