This assertion about the general expectation needs proof. If true, then
legacy Microsoft fonts which use the same metrics for the © and ®
symbols have been wrong "since long". As far as I can tell, the symbol
is normal sized when used in running text. It only appears to be an
annotation when used in conjuction with a logo. It's true that
appearing with a logo is a most likely spot to find it. But logos and
their annotations need rich text. It could be argued that the EMI logo
appearing in a scan linked recently has the ® shown at a perfectly
normal size, and that it's the logo which has been made so incredibly
larger that it hangs way below the baseline. Logos on various products
are designed to be large and to stand out. Sales and Marketing 101.
We might also look at the origin and if all source character sets
unified into the original Unicode had this symbol superscripted, we
could state that historical fact.
But suppose they don't. Legacy charts, as I recall, show the © and ®
symbols as having the same metrics. Like in this chart on page 10:
