ESI for older browsers, and JavaScript otherwise are still on the table, but that's orthogonal to the varnish cache purge -- if we use ESI, the banner will be cached and will need to be purged.

For sure; I just wanted to make sure. While practically these may be orthogonal, purging full pages is less desirable than purging html chunks for banners so approaching the problem with this in mind might make it all more palatable.
