Required *for comment-start*? No. What does the docstring for
comment-start tell you?

    String to insert to start a new comment, or[…]

The space is there so that when the string is inserted, the user will
be able to start typing the comment text and it will be separated from
the delimiter.

    # comment in shell or Python
    ; comment in Elisp
    // comment in C++
    /* comment in C */
    <!-- comment in HTML -->


Required for *your use* of comment-start? Maybe.

Anyway, what’s your plan for modes whose comment-start is longer than
a single character after trimming the space?
