[hibernate-dev] Should the TransactionSynchronizationRegistry be cached by the JtaPlatform or perhaps at the SessionFactory level?

Hi, I started working on a WildFly change WFLY-11243 [1] to cache the TransactionSynchronizationRegistry inside of the WildFly JtaPlatform instance. The purpose of caching the TransactionSynchronizationRegistry is to avoid repeated JndiService.locate() calls, like during entity manager creation time [2] and other uses as well. My question is whether the idea of caching the TransactionSynchronizationRegistry instance is already handled at the session factory level? If not, would that make sense? [3] is the WildFly pr to cache the TransactionSynchronizationRegistry instance, to avoid repeatedly looking it up (since it rarely ever changes). If there is a way to instead have the TransactionSynchronizationRegistry cached at the SF level, that might be better.
