Yes:

1) editorially, don't use the term "subscribe" since it is NOT a
subscription, it's a sub-list[s]; subscription of lists to lists add more
LISTSERV anti-spam "gotchas"

2) if the poster to list B is a subscriber to sub-list A, it is possible
under some release of LISTSERV that they will not get their own message
even if they are in REPRO mode (this can be very disconcerting)

3) subscribers to sub-list A will "see" the mail distributed to list B as
originating from B i.e., they see nothing to indicate that the mail
involved sub-list A

4) only LISTSERV maintainers may add the list-definition keyword SUB-LISTS=
