Hm, maybe it should be patched or branched then since all this code
duplication is not great.

It has been a problem for years now. If it gets solved soon - all the
better. Still it is annoying that taglib cannot be reused.

That would indeed be best. And if Strigi's indexer get as good as Taglib
we do not have a problem anymore. :)
