"JSF" throughout source code must be renamed to "Jakarta Faces" or at least "Faces". No abbreviations.

For JavaScript:

• Rename jsf.js file to faces.js
• Rename window.jsf variable to window.faces (so jsf.util.*, jsf.ajax.*, jsf.push.* become faces.util.*, faces.ajax.*, faces.push.*)

For JNDI:

• Rename jsf/ClientSideSecretKey to faces/ClientSideSecretKey
• Rename jsf/FlashSecretKey to faces/FlashSecretKey

For passthrough elements:

• Rename xmlns:jsf to xmlns:faces.
• Advocate new namespace prefix in documentation (e.g. "such as <input type="text" jsf:id >" must become "such as <input type="text" faces:id >"

For log strings:

• Rename key jsf.* to faces.*
• Rename text "JSF" to "Faces"

For impl:

• Rename com.sun.faces.facelets.tag.jsf package to com.sun.faces.facelets.tag.faces
• Rename Jsf / JSF / jsf in method/variable/class names to Faces / Faces / faces
• Rename mojarra.jsfcljs to mojarra.cljs

Doubts:

• https://jakarta.ee/specifications/faces/2.3/apidocs/javax/faces/webapp/prejsf2exceptionhandlerfactory I'd rather get rid of it.
• jsfc attribute - the newer passthrough elements feature should be used instead. Moreover, the jsfc attribute was never officially mentioned in original Faces API specs, it just sneaked into Faces impls as part of Facelets.
