I'm author of sqlbind[1] and since t-strings announce have been thinking really hard how to incorporate it. Like obvious cases `t"select * from table where id = {id}"` are tempting only at first glance. But simple queries could be written by other means. Dynamic ones where you should drop part of query by some condition is a real problem.
Your solution is impressive. It would be quite hard to support crazy sql extensions, for example for ClickHouse but as a concept it really ingenious.
