Search field: {template}

Search for: empty
Replace with: empty
Destination field: identifiers
Identifier type:*
Mode: Replace field
Split Result: Unchecked

Yes, except you should leave Split Result checked so that each comma-separated item is treated as a separate identifier. If you uncheck the box then SR tries to treat the string as 1 identifier and will complain that it finds too many colons.

Do I care about this possibly creating an extraneous trailing comma?

No, as long as there aren't any non-blank characters following it. Null items are ignored, which means that ",,,,,,,,isbn:12345,,,,,goodreads:81267,,,,,," is also OK.
