It depends on the form of the conflict.

I believe that the IESG has the duty to ensure that concurrent
experiments either use experimental codepoints in non-conflicting ways,
or else require them to use distinct codepoints; to fail to do this
creates the risk that any experimental results will be
muddled/contaminated.

In this case, the two experiments interpret the same codepoints in the
DNS in subtly different ways.

A mail-sending domain indicates that it is participating by publishing
certain DNS RR's.
Crucially, a mail-sending domain cannot opt in to the SPF experiment
without also opting in to the senderid experiment.  This renders any
claimed results of either experiment suspect.
