I can't remember the exact timing (Ned probably would), but
there were also VAX/VMS machines running native Internet stacks
and PDMF by that time.   VMS, IIR, preferred to use records with
length counts rather than any flavor of line terminators.    But
that doesn't change your conclusion about MSDOS having nothing
to do with the decisions -- as I think someone else pointed out,
CRLF was established as a convention for email messages with
mail-over-FTP, long before even 821/822.
