drop the single line secret format

and/or use a more structured format for the secrets

[thatportugueseguy]

is this still relevant? I think with the current handling in the code, single/multi line secrets have less clashes (my guess, no feedback for a long time).

And adding a new format for the secrets feels like too big of a change, considering the roadmap for the product..

I think going to a more unified format would still be relevant. We know that we want to extract the comment out of the secret at least. And that we don't want to deal with too much legacy.
