If Microsoft want to examine the From header then that is their

The problem is that I publish SPF records for my domain in the expectation
that they'll be used correctly. By behaving incorrectly, Microsoft
is making it less attractive for sites to publish SPF records lest they

I hear you.
I don't think it diminishes the effectiveness of SPF though. If your
domain is regularly spoofed/phished etc then publishing an SPF record
provides a really easy way for your recipients to verify your mail is
legitimate and weed out the spoofs.
But of course that is dependent on the receiving mail server being
competently configured, something which is outside of your control.
