That's basically just C and a few of its descendants, notably Java and Go.

so if this RFE goes through, I'd suggest it use
that syntax

Respectfully, I think that's a bad idea.

In my opinion, a more worthwhile idea to consider is whether to
explicitly support arbitrary expressions (like JavaScript, Python, C#,
and others), not just individual variables.

I also think, that the old/classic C-like "%s" syntax would be "one small step" ... whereas a real variable interpolation like "abc{variable}def" would be "a giant step".

Variable and arbitrary expression substitution and additional formatting flags would be very good - and it seems not so hard to implement.
