Something I mentioned during the SRFI-261 draft was that every SRFI
should have an identifier. I think the SRFI template should have an
"Identifier: " part (for example, after the title or the authors at the
top of the SRFI) to encourage people to assign names. I forgot that the
metadata field existed until recently, and making it more prominent will
make more people assign them to the SRFI.

Having a Scheme identifier for every SRFI is useful, even for ones that
don't provide libraries, because they can be used by a future extension:
for example #!raw-strings-267 to enable raw string syntax.

Making it a decision by the author of the SRFI also makes it normative,
which is important for stability.
