-1 You will end up breaking anyone that has written any scripts/plugins/apps on top of pre 3.x CS. Since UUID was introduced in 3.0, you should only accept the following:
- All first class objects created before 3.0 should accept an normal internal ID. - All first class objects created after 3.0 should accept UUID only. Any attempts to query these objects using the internal ID should result in "object not found". By forcing everything to take in a UUID means you will have to force many of CS's integration on top of pre 3.0 CS to re-map their internal IDs. This is just not practical.
