It is almost one year since the release of JNLP4 protocol in Remoting 3.0. This protocol is available in Jenkins LTS since 2.32.1, and so far it demonstrates good stability being compared to JNLP2 and especially to JNLP3. The protocol was enabled by default in 2.46.x, and we do not have confirmed JNLP4 issues since that.

I propose to disable the previous protocols
