The first-page of the paper has 13 co-authors listed - but all with the same affiliation ("Google, Inc") - so this is ultimately a single-vendor making a unilateral proposal to break with the past - which means I'm confident this proposal won't be gracing the pages of the ISO/IEC 9075 (ISO SQL) standards in my lifetime - no matter how badly we all need QoL improvements to SQL.

...okay, if I dial-back my feelings of resignation to mediocrity, then I'll admit that Google probably does have enough clout to make this go somewhere - but they'd need to add this to all their database offerings (BigQuery, Spanner, Firebase's SQL mode) and contribute patches to Postgres and MySQL/Maria - maybe after Microsoft relents a decade later to add it to MSSQL we'll maybe start to see Oracle's people refer to it vaguely as a nice-to-have they'll implement only after they start losing more blue-chip customers[1].

Also, it's giving me M (Excel PowerQuery) vibes too.

[1]For context, Oracle's DB lacked a `bit`/`bool` column type for the past 40 years until last year. People had to use `char(1)` columns with CHECK constraints to store '0'/'1' - or worse: 'T'/'F' or 'Y'/'N' (see https://stackoverflow.com/a/3726846/159145 )
