p=reject: all mail sent from this domain should be aligned in a DMARC

some of our authorized senders' mail is rejected too.

As soon as this specification text, here, contains language about how this information is to be used, should be used, or could be used, it crosses over into creating confusion about expectations of receiver handling.

I agree with you, which is why I said "believe" and "request".

If we're going to have any description of p=none at all it needs to emphasize the point that it's telling you that they consider the messages unusually unimportant. This appears to be at odds with what some DMARC users believe.
