Actually the - in the beginning of the name means that it is a login
shell. (You probably already know that.) But it is true that a login
shell will always be interactive.

In a non-interactive shell, or an interactive shell in
which the -o interactive-comments option to the set
builtin is enabled, a word beginning with # causes that
word and all remaining characters on that line to be
ignored. An interactive shell without the -o interac
tive-comments option enabled does not allow comments.
I can see how you could infer from the above that interactive-comments
should be off by default. But, strictly speaking, the above paragraph
does not say that. It just talks about the behavior of an interactive
shell without the option enabled.
