Description
Hello there,
we detected a weird behavior when serializing UUIDs. Some of them, such as 0054971b-b746-4776-ae7a-d942cd511393, are quoted during dump, whereas others, such as 0645cada-c729-48cb-a4e3-9d8cbc7cb510 aren't.
The observed behavior seems related to this commit created to fix this issue with floats handling.
The YAML 1.2 schema uses this regexp /[-+]?(\.[0-9]+|[0-9]+(\.[0-9]*)?)([eE][-+]?[0-9]+)?/ to match floats, but on Psych side this regexp is used: /\A0[0-7]*[89]/, which leads in my understanding to an inconsistent behavior.
I'd be glad to craft a PR but I' not sure whether Psych behavior is expected or not.
Thank you :)

Research direction
Start by reproducing the two UUID serialization cases in Psych and read the referenced commit b737f0811a9687cf86f44f0a35f61cbde9eac673 alongside the YAML 1.2 float-matching rule. Confirm whether the differing quoting follows the intended schema, then define a regression test for the agreed behavior.
