:width is an ATTR_LATEX keyword, as is :options.  So they only apply to
the LaTeX backend – and those which derive from it, such as beamer.  If
document authors wish to also export to e.g. HTML, they will have to
make separate arrangements.

Eliminating subtleties is precisely the point of this change.  All(-ish)*
backends now use :width.

* As far as I’ve checked, HTML(+ derived backends) and LaTeX(+derived
backends).  If there are any that don’t, they should probably be patched
to do so as well.
