FWIW, it seems to me one case where this happens is when you want to
use one argument multiple times, without naming:
'<{0} id="{1}"> {2} </{0}>'.format(tag, id, content)
Arguably, this specific example would look better with named references,
but, IMO, not with % formatting:
'<%(tag)s id="%(id)s"> %(content)s </%(tag)s>' % dict(
tag=tag, id=id, content=content
)
and as noted, f-strings have their limitations.
