Let's first define Standard users. The majority of users who use
smartcards that *I* know are expert or power users. They can handle this.
The "Standard users" I have in mind don't use GnuPG for anything else
than encrypting mails, and they don't use smartcards either. They won't
have this issue in any way.

For which use-case precisely? If you only use OpenPGP for emails (and
given the users I know who had support cases in the past, this is true
for the majority of the Enigmail users), then this is irrelevant.
To be quite clear: Thunderbird will not support GnuPG for scenarios
other than handling secret keys. And that's only because the OpenPGP
library they use can't handle smartcards yet. Once the library will
support smartcards, I expect that GnuPG support will be removed entirely.
Note: I'm not a Thunderbird developer and I don't drive Thunderbird
decisions -- this is simply my expectation of what will happen.
