For the originally floated idea, that would mean WP admins could set something
like:

in a user talkpage to avoid constant edit-warring (or endless debate about
guideline about) removing/readding active block messages. An additional use
might be in [[Template:Lu]], where this same logic could be used to display an
icon or other status indicator. This would be useful in sock-puppet and related
abuse discussions to reveal at a glance the status of the account(s) being
discussed.

It should be {{ISBLOCKED:USERNAME}}, not with "#".

This sounds like an awful idea, suggest WONTFIX.

We'll have to vary pcache expiry on block expiry times?
