It is left anchored with "^" so it would be hard to match more than once on the same line ;-)
I agree that it is the right solution to make the whole thing case-insensitive by adding 'i' at the end.
FWIW, the RFC first says this:
1.2.2. Syntactic notation
This standard uses the Augmented Backus-Naur Form (ABNF) notation specified in [RFC2234] for the formal definitions of the syntax of messages. Characters will be specified either by a decimal value (e.g., the value %d65 for uppercase A and %d97 for lowercase A) or by a case-insensitive literal value enclosed in quotation marks (e.g., "A" for either uppercase or lowercase A).
and then goes on to define how message-id should look like.
3.6.4. Identification fields
message-id = "Message-ID:" msg-id CRLF
But if you go the "add /i at the end" route, you do not have to upcase "d" to "D" and that may reduce the patch noise (it only matters if the patch viewer highlights letter-by-letter changes for your recipients).
