I can't see any reason why CL (or EGISYS, who I believe may have had more involvement in the Content room development) decided to implement this in functionality in Python, even if upgradability was an issue, there are plenty of alternatives. And, of course, the risk of Trojan Horses may put people off using Python scripts, which would be a shame, especially for those of us who are interested in developing substantial plug-ins using this interface.
