I partly agree, but I also think the stamp-like nature serves a purpose. Note that deprecated members and restricted methods use the same format, sometimes adding a full sentence:

https://docs.oracle.com/en/java/javase/24/docs/api/java.base/java/lang/Runtime.html#method-summary
https://docs.oracle.com/en/java/javase/24/docs/api/java.desktop/java/applet/Applet.html#method-summary 

So I think it could be improved, but should be part of an effort to improve marking of "special" elements in general.
