Fixed spaces, in any sense of the word, is an anachronism. They were
"fixed" in lead, but any modern tool has more convenient means to
achieve the desired result. For XSL-FO, there are space-start and
space-end attributes for inlines, for example. Any usages you provided
for them (long number separation, comma separation etc.) could be best
accomplished with exactly specified margins between inlines. This is
the way to specify "typographic" conventions better than the font
creator may have in mind when designed "thin", "hair", "1/17em" or other
pre-defined fixed-width spaces.
