If it's not a completely new library written exclusively around templates, such code currently accepts strings and will most likely continue to accept strings for backwards compatibility.
In that case I don’t understand the security regression that t-strings cause (see GP). Before it was all just strings, but you had to make sure to use them in the correct place. Now you can still just use strings for backwards compat. but you can also move on to a distinctly-typed solution for SQL and the like.
