One thing that I couldn't figure out is how to get rid of the width
specification altogether. I can change the default
[...,width=0.9\textwidth] with something like

  :width 10cm

but if I scale the image (presumably by trial and error until
it looks good to my eye), then I want to turn off the width
option altogether (afaict, latex treats [scale=1.5,width=10cm]
as [width=10cm] - scale is not considered at all, hence my desire
to turn off width.)

I tried

  :width nil

and

  :width

In these cases, I get the default. The code looks like this

--8<---------------cut here---------------start------------->8---
	 (width (cond ((plist-get attr :width))
		      ((plist-get attr :height) "")
		      ((eq float 'wrap) "0.48\\textwidth")
		      (t org-latex-image-default-width)))
--8<---------------cut here---------------end--------------->8---

and in these cases the plist-get returns nil, so the t clause
triggers.

I also tried 

  :width ""

which fails with a

Wrong type argument: stringp, nil

in this call (and I haven't chased it further):

--8<---------------cut here---------------start------------->8---
	 (attr (org-export-read-attribute :attr_latex parent))
--8<---------------cut here---------------end--------------->8---


Is it possible to eliminate ``width'' from the options?

I don't understand: what do you mean? AFAICT, you *have* to say 

 :placement [htb!]

*including* the square brackets, because the first clause of the cond
triggers and that does not include the square brackets:

--8<---------------cut here---------------start------------->8---
	    (cond (place (format "%s" place))
		  ((eq float 'wrap) "{l}{0.5\\textwidth}")
		  ((eq float 'figure)
		   (format "[%s]" org-latex-default-figure-position))
		  (t ""))))
--8<---------------cut here---------------end--------------->8---

OTOH, here you don't want to include the square brackets because the
format *does* add them. That seems to be a slight inconsistency.
