A bit of a bizarre post since to_sgid has existed forever to generate signed global ids. Global IDs are probably one the most powerful and underrated features of Rails but regular global ids are only supposed to be used internally (e.g. job params) and never sent to the client.
If there’s a gotcha it’s that _signed_ global ids are only signed, not encrypted, and very few people seem to know about the optimised method (globalid::Locator.locate_many) for loading a batch of global ids
