OK, this is less of an issue than I originally thought. My original concern was for applications like caff, that want to do things separately on the side, so as to not pollute the user's keyrings. But looking at them, they all seem to work on public keys only, rather than secret keys.
But maybe a future one will want a separate pool for secret keys. So it would be good to add a --auto-launch-agent option, to automatically launch a new gpg-agent if the current one has a different --homedir.
At least, the manual page should be updated to say --secret-keyring is now ignored (and to point to the new location).

Yes, this is gpg-agent 2.1. I'm using --edit-key --expert then addkey. It prompts me for a passphrase for each new subkey.

Well, at least it should say the keyid, whether it is a subkey (what use-flags) and (if so) which master key it belongs to?
I like the gpg 1.4 prompt - it's informative, when I sign something and it prompts me to unlock, it says:
"You need a passphrase [...] for user <UID>, 4096 RSA, subkey $ID, created $date (main keyid $ID)."

In DETAILS.gz, it now says:
* Unattended key generation
Please see the GnuPG manual for a description.
Previously (with gpg 1.4) it contained the actual documentation. Perhaps Debian should just package the manual.
With gpg 1.4 (and it seem the case for 2, ), there was a bunch of things stopping me from writing this script  using batch mode. The main blocker was:
This generates a secondary key. Currently only one subkey
can be handled.
but possibly there was more, I can't remember.

OK, my motivation was that not having a prompt makes the input flow more consistent, so easier to script with. But probably the best solution is to fix batch mode (and maybe make it work for an existing key) rather than to make the CLI "more scriptable".

(1) RSA (sign) and RSA subkey (encryption)
At least, the (9) ECC option should make it clear there are two keys being made. As dkg pointed out, it is extra confusing when mixed with (10) and (11).
(9) ECC (sign) and ECC subkey (encryption)
(9) ECC and ECC
This would also match the existing (1) RSA and RSA.

As I understand, C/S/A all treats the public key as a signature scheme. You can tweak the suggestion, e.g. "(set your own capabilities, except encryption)", the point is to distinguish it from keytypes that can actually support all capabilities.
There is no way to "go back" in the CLI, so I have to quit the whole program if I pick the wrong option. Maybe then we can add a "back" option?

That is true, and I can use ElGamal in the meantime.
