exim acl recursion is limited to 20 iterations, so there is no way to
produce any damage to a Exim server. Nevertheless there will be no
recursion if there is no real recursive SPFIncludes published. No data
produces no recursion.

It took me 10 minutes to publish spf info for about 200 domains. I also
do not understand your objections to how spf scales. As I know you could
spf-allow a whole C class with a single line of configuration.
