No. Neither DKIM nor SPF have any connection to either the From: or
Sender: header other than what DMARC is trying to do.
DKIM has a required hash bind to the 5322.From field data -- the only 5322
header signing requirement in DKIM. It's burned into the now DKIM now STD
level specification. That's not a DMARC requirement, but one DMARC relies on
having with DKIM.
Maybe an errata is in order?
