My assumption is that some SPAM filter then sees this results, can't make
much sense of it and marks the mail as SPAM.
we (medium size ISP in germany) do double signind since years.
But we have not yet seen a "bad reputation" based on the ed25519 signatures.
Some modules have a logic like so:
score DKIM_SIGNED 0.1
score DKIM_VALID -0.1
score DKIM_INVALID 0.1
score DKIM_VALID_AU -0.1
That way, an invalid DKIM signature weights 0.2.
Best
