It would ideally need something more nuanced, like a list of globs to 
match and a list of globs to ignore, so that, for example, new files 
could also be added to the index.

And also the directory structure(s) involved (see my previous example of 
two dirs side-by-side)... overall, this seems like a difficult direction 
to proceed when we have an automatic approach for generating tags with 
its own settings already.
