I second that. Some of the many BibLaTeX commands are due to
compatibility with other (older) packages and to ease transitions.

Another aspect: Maybe it would be a good idea to reserve some chars
(e.g. the numeric ones) for user defined citation commands (a
minimalistic reserved namespace).

I personally also dislike one keyword for completely different
purposes. Therefore I suggest to take the idea from BibLaTeX and use a
keyword like "printbibliography" the mark the place where the
bibliography should be output.

This command may also have parameters like filtering options (maybe
depending on the backend processor; I only know BibLaTeX so I can't
say if it would be easy to abstract away differences between different
engines). In the case of BiBLaTeX the printbibliography command
optionally accepts multiple key-value parameters. Some examples for
the keys are "heading" for the chapter/section heading, "type" to
output/print only entries of a certain type (like "book"; or type
"online" and with the additional key "nottype" separate non-online and
online sources), "keyword" to filter entries with the associated
keyword etc.

Another nice feature of BibLaTeX is the possibility to generate
bibliography per chapter/section (e.g. setting conference
proceedings). In the simplest case each chapter/section is marked, in
the case of LaTeX/BibLaTeX it is wrapped with "\begin{refsection}" and
"\end{refsection}" and the printbibliography command occurs inside
this refsection block. In this case BibLaTeX defaults to output only
references used inside the marked block.

Yes, I second that. But it may be worth thinking a second about using
one Org document to generate output with different backends (e.g. PDF
via LaTeX and BibLaTeX, HTML, and ASCII). It would be nice, to have
some way to configure each citation engine form the same document.
Either use different keywords like "#+CSL_STYLE" and
"#+BIBLATEX_STYLE" or we use your original suggestion of a ":style"
parameter to the "#+BIBLIOGRAPHY" keyword and provide some means to
translate its value individually for each engine - e.g. an alist or
some function provided by the user. And if no translation is provided,
just give the value verbatim to the engine, thus if a user only
targets a single backend, he does not need to provide any
extra configuration.

Just my 2ยข.
