[AMRadio] Is AM a special case, or is it "just another mode"?

Hello from one who started out 58 yrs ago on AM, and who today - like 
yourselves- restores, recaps, and owns and operates lots of AM boatanchors !

I read Dave Summer's Editorial on "Symbol Rate" and don't see anything 
where he is delineating AM to "just another mode"

Must be missing something, for what I read is :

        "That the ARRL Board would like to have the adoption of a 
bandwidth limit of 2.8KHz for amateur _data _transmissions below 29.7 MHz.

Summer  also states that :

" It is important to note that _the limit would only apply to "data" 
modes _in the subbands where RTTY and data are authorized emission types 
and not to either
_analog _or _digital_ _phone emissions. __

_Thus,  am in agreement with Jim, W5JO's, comment :

  " From what I see there is nothing more than an attempt to change the 
symbol rate for digital communications and _nothing is in there to 
affect AM__. _
_
_ _But given the ARRL's history everyone must be vigilant ."
