Every supplier has its own "standard" here - due to specific interests

Well, that's no surprize: cwm looks like nothing! It's zero width and
would print less than a space on paper ;-)

The reason are simply of technical nature and not intended to drive you
crazy! nbspace stands for a repeated entry of space, actually to avoid a
repeated entry in the encoding, stfhyphen has the same function
originally but can be utilized by Tex for either hanging hyphenation or
improved hyphenation of compound words for the English Latex version.
The presence of cwm is used for some internal processing in the kern/lig
machinery of Tex.
You see every little bit has a purpose...
