PIV slots on the Solo v2

[smlx]

The Solo v2 specifies that it implements PIV. However I can't find any detail on the implementation. In particular I'd like to know if the Solo v2 will have multiple slots the same way that the e.g. a Yubikey does (https://docs.yubico.com/yesdk/users-manual/application-piv/slots.html).

If so, which slots will be implemented?

From the looks normal NIST will be implemented for PIV. Also found out gnupg already supports piv and just needs to be added to the scdaemon for application type as it will default to the gpg applet before piv.

Maybe I'm mixing things up, but as far as I remember the spec does not mention multiple (equal) slots or even opposes against having more than one.
Again only from faded memories only, the YubiKey works around this (and still be NIST compatible), by declaring those additional key slots "retired keys", stating, they are for deprecated / expired keys, in order to still be able to decrypt old messages.

Quote from YubiKey docs:
"Slot 82-95: Retired Key Management

These slots are only available on the YubiKey 4 & 5. They are meant for previously used Key Management keys to be able to decrypt earlier encrypted documents or emails. In the YubiKey 4 & 5 all 20 of them are fully available for use."

whereas slot 9{a,b,c,d,e,f} are for the primary key (letters indicate different crypto-purposes).

What I would really love to see and what the YubiKey does not: allowing *25519 keys/certs in those (additional) slots.
