SuiteCRM 8.2 - Will there be ongoing support for the Legacy V8 REST API?

I’d like to know what the ongoing plan is for API support in SuiteCRM 8.x? I know there’s now technically 3 APIs. The old V4 one (I think), the V8 REST one, and the new GraphQL one.

I’m currently running a site using the V8 REST version. I’d like to upgrade to SuiteCRM 8.x but don’t know if the V8 API is now on the path to deprecation? Will SuiteCRM 8.x continue to fully support the V8 API for it’s lifetime? If fixes are needed can I still submit GitHub pull requests for the “legacy” API?
