This JEP doesn't propose to deprecate the agent mechanism, it's an 
explicit non-goal to deprecate it. Instead it's about emitting a warning 
when a native or Java agent is loaded at runtime.  Separate work for JDK 
21 has added a JFR event when agents are loaded as it is useful to have 
in a recording too.

Most JEPs may be about new features but JEPs are also used to 
communicate significant changes,  deprecations, and removals. If you 
look through the list of JEPs [1] you will find several on deprecation 
where the authors have put consideration effort into explaining the 
motivation.
