I hope my question does not come off as too aggressive, but why on earth are
we still using BibTeX? Or, more accurately, when can we _stop_ using BibTeX
and move onto something that has native UTF-8 support and can also integrate
with a reasonable configuration environment such as CSL?

What is the next step for bibliographies in Context? Surely we won't be
chained to BibTeX (which has seemingly been largely been in practice for the
sake of BibLaTeX) forever?
