Well, yes, I'm proposing a filter. Filters by their nature have to be 
converted to HTML on output. Drupal does a fair bit of filtering and can 
do a lot more. I don't really understand the problem you have with this 
proposed solution; just using HTML doesn't solve...well, anything, since 
the base tag is no longer used the way it was in 4.6.
