Okay to summarize:

For gnome-keyring we'll go for parallel installable libraries, and
during the 2.91.x series make it work like option (a) above. Right now
we're a solid (b).

For seahorse and seahorse-plugins we won't do parallel at all, as
Matthias suggested.

libgnome-keyring doesn't touch GTK at all, so not an issue.

gnome-keyring is used by other desktops, so I imagine a GTK2 version
will be appreciated for the time being.

Roger. Thanks.
