Yes, but

are fo character siblings in the XSL-FO sense but not fop internally. 
The suggestion to move white space handling to inline will not cover 
this case.

Not quite - see above - because fops internal distinction between text 
and fo:character.

I am still of the opinion we are better off to do as much white space 
handling, including white-space-treatment during refinement. Only 
white-space-treatment around "soft breaks" need to be deferred to the 
line breaking phase during layout.
