I think the idea of global tokens is rather weird. Now, tokens are
always local to a single t() call. If tokens are shared between
strings, this is only because it is explicitly done by the coder. If
we start making some tokens globally available, there is absolutely
no argument against adding more arbitrary tokens to this list. It'll
explode into a zoo of random variables.
I think we perhaps do need to look at a way of using e.g. PHP code in
these welcome mail-like strings. That way, you can use arbitrary code
to retrieve any value you need. You could even make it backwards
$text = strtr(drupal_eval($text), array('%token' => ...));
if no <?php ?> tags are used, it reverts to simple strtr() replacement.
