The use of ro in combination with the script ID Cyrl would be entirely reasonable. Also, in a particular application context, people can choose to continue to use mo/mol if that is permitted by that application context: we haven't un-assigned mo/mol, we've just discouraged the use of those IDs.

Subject: Fwd: Re: ISO 639 JAC decision re mo/mol
See forwarded message. I was expecting some people not to be very happy about this decision. I hope we are not overwhelmed by letters of disagreement. Of course the answer is that we are standardizing the code, not the language name, and that the code is an identifier, not an abbreviation for the language. And that Moldovan is a variant of Romanian and can use the script code for Cyrillic.
If anyone has additional ideas for an explanation of our decision, please let me know.
