Only if you're really desperate to make a "premature optimisation"
argument.

The alternative, i.e. to use a higher-level but less efficient language,
results in the optimisation never being performed at all, even in the
finished product.

Some optimisations must inherently be performed at the outset, if they are
to be performed at all. If you adopt an approach which is structurally
inefficient, then the only way to get rid of the inefficiency is to start
over with a more efficient structure. That doesn't make such optimisations
"premature".

Premature optimisation means performing "optimisations" before you have
sufficient knowledge to determine what is actually optimal.

This is primarily a problem with "code first, design later" development,
where you don't really know what you should be doing until you have a
working prototype (either because the problem isn't amenable to structured
development, or the programmer isn't).

OTOH, if you have a good understanding of the problem, it's entirely
possible (and reasonable) to make optimisation decisions long before you
start writing code.
