Python’s new t-strings

All things considered, this is pretty cool. Basically, this replaces

    db.execute("QUERY WHERE name = ?", (name,))

with

    db.execute(t"QUERY WHERE name = {name}")

Does the benefit from this syntactic sugar outweigh the added complexity of a new language feature? I think it does in this case for two reasons:

1. Allowing library developers to do whatever they want with {} expansions is a good thing, and will probably spawn some good uses.

2. Generalizing template syntax across a language, so that all libraries solve this problem in the same way, is probably a good thing.

Aren't there other benefits to server-side parameter binding besides just SQL-injection safety? For instance, using PG's extended protocol (binary) instead of just raw SQL strings. Caching parameterized prepared statements, etc.

Also:

    db.execute(t"QUERY WHERE name = {name}")

Is dangerously close to:

    db.execute(f"QUERY WHERE name = {name}")

A single character difference and now you've just made yourself trivially injectible.

I don't think this new format specifier is in any way applicable to SQL queries.
