A decision should be made about that. Does (srfi <number>
<sublibrary-name>) make sense or not, given that (srfi <number>
<srfi-name>) exists?

We already kind of do. In R6RS we use (import (srfi :123)). It's wise to
prepare for a scenario where R6RS and R7RS are merged, and some of the
implementations additionally support keywords with : prefix syntax.

Then we'll have some implementations in the wild that parse the :123 as
a keyword and others that parse it as a symbol. It's may be prudent to
treat keywords the same as symbols while dropping the "#:" prefix, ":"
prefix, or ":" suffix. Common Lisp already does something like this in
common usage of `defpackage`. Uninterned symbols "#:" are treated the
same as keywords ":". Only the symbol name is considered.
