Well, then you are wrong. I mentioned several other points and mentioned
them countless times.

I either need a separate file or I need an enclosing form.
With "toplevel" I mean s-expressions at the outermost level, not
nested inside other s-expressions. Now, is that clearer?

I probably understand it more than you do. I have in fact implemented
it once. So please beware of false assumptions.

Huh? Look at some existing Scheme implementations, say, guile, gauche,
PLT, chicken, they all use some form of REQUIRE. I'm a pretty regular
reader of c.l.s and of several Scheme mailing lists, and I can't remember
hearing any complaints about it. I haven't heard anybody screaming for
SRFI-7 either.

In what way is it strange? REQUIRE, USE, USE-MODULE - it's all there.

Your definition of "technically inferior" is strange. Ask PLT users
whether they find REQUIRE is technically inferior.
