The message was meant to be "don't abuse" markup in data;
Don't attempt bibtex/latex hackery.

As Hans mentions, \btxcommand was introduced to handle some formatting
in bibtex entries that might be inconsistent or in conflict with
standard ConTeXt commands. When no \btxcommand definition is found,
the system falls-back on standard ConTeXt (or luatex) syntax. Sloppy
bibtex files should be cleaned up, but the aim is to allow files to be
shared with bibtex/latex (minus any hackery, which could/should be
fixed in the bibtex style files, but usually is not).
