However, to get back on-topic, since people DO do this type of thing,
perhaps a note in the FAQ (is there a FAQ?) regarding the use of more
than 10 records for any particular mechanism won't be handled in a
predictable manner or may even invalidate their SPF record altogether.
In the case of using MX for load balancing, the SPF record does
not have to use an MX mechanism. In the case of netcom.com,
all the servers are in a subnet, so an mx/24 would work reliably (doesn't
matter which of the records it sees first since they are all in the same
subnet), but even better would be an a:mx00.netcom.com/24 or
ip4:207.69.200.0/24.
