Yes, one way or another the "wallet" will be aware of what options are
available and can decide what to use algorithmically or present choices
to the user. Part of what is being discussed here, however, is how the
browser knows about your "wallet" and therefore what options have been
associated with the user. It could be through a registration process
that must be repeated on every device/platform, there could be some
syncing protocol, or there could be a discovery mechanism.

There is overlap here with what's being discussed for Web Payments and
with Credentials. In the Credentials CG, we want the "wallet" to be
associated with the user (credential holder), so it can follow you
around, instead of being strongly linked to a particular platform or
device (this causes lock in and reduces user choice and competition).

Therefore, a discovery mechanism is implemented in the demo. We have
more work to do to better demonstrate that this can be used across
different devices.
