...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 )
If you are truly blessed you get to see all of these in a single database. Also “Yes”/“No” with that specific casing.
You can guess how many foreign keys that database had.
Piped SQL fits in perfectly with the overall SQL pot-luck buffet! I for one welcome Google to the table, enjoy the language that works everywhere and nowhere but is the best there is.
