Suppose your analysis stack includes lower-casing, but your synonyms are

Mike, thanks a lot for your example: the idea here would be you would
put the lowercasefilter after the synonymfilter, and then you get this
exact flexibility?
e.g.
WhitespaceTokenizer

your synonyms with just the tokenizer
Yes, I see. Makes sense. It is a bit hard to see a bad case for your
proposal in that light. Here is one other example; I'm not sure whether
it presents difficulties or not, and may be a bit contrived, but hey,

synonyms?
For example:

the FieldAnalyzer Solr http call, then save the final chewed-up terms
as a new synonym file. You then use that one in the analyzer stack
below the stemmer filter.
