I am optimistic concerning that patch since a couple of users confirmed 
improvement, but it is up to John to decide if it is acceptable in 
comparison to org-ref. I am unsure concerning startup time.

Anyway citation style is rather specific for a particular CSL style. I 
tried some styles: 
https://github.com/citation-style-language/styles/blob/master/ieee.csl 
https://github.com/citation-style-language/styles/blob/master/american-physics-society.csl 
nature.csl science.csl and for all these styles even "author" is 
meaningless since they are numeric styles.

So it is not more general. Switching CSL style means necessity to update 
styles in each citations (unless it is possible to specify global or 
per-cite mapping).

It seems modifiers are set of boolean flags (positive "year" or negative 
"suppress-author") in citeproc.el, set of values in natbib, and a kind 
of hierarchy in org-cite. From my point of view, set of constrains 
(flags) is the most general variant in this list.

I agree. Negations are more confusing when an author needs just year.

I would say that if a citation style has no year than a warning should 
be spat, but year should not appear since it is against the style. 
Unsure if it is useful to have special command or style "query" that can 
insert e.g. year, journal, or any other field disregarding style to 
ensure that the text and the bibliography reference have not diverged, 
but it is rather for descriptive text than for a citation.

A fallback style (for the particular citation, for the whole document or 
in global user preferences) might be specified for formatters missed in 
the main style.

I have tried the following:

obt.bib:
@ARTICLE{schawlow1958iao,
  author = {Schawlow, Arthur Leonard and Townes, Charles Hard},
  title = {Infrared and Optical Masers},
  journal = {Phys. Rev.},
  year = {1958},
  volume = {112},
  pages = {1940--1949},
  month = {Dec},
  doi = {10.1103/PhysRev.112.1940},
  issue = {6},
  publisher = {American Physical Society},
}

obt.org:
#+bibliography: obt.bib
# #+cite_export: csl
# #+cite_export: csl 
/usr/share/citation-style-language/styles/chicago-author-date.csl
# #+cite_export: csl 
/usr/share/citation-style-language/styles/american-physics-society.csl
- Default: [cite:@schawlow1958iao].
- text: [cite/text:@schawlow1958iao].
- noauthor: [cite/noauthor:@schawlow1958iao].
- year/bare: [cite/year/bare:@schawlow1958iao].

#+print_bibliography:

I am familiar with bst language used by BibTeX and I am surprised that 
initials instead of full names are not enforced by CSL styles. Emphasis 
and bold markers may appear in plain text export. Behavior of styles is 
not uniform in respect to adding (unbreakable?) space before citation.
