I think the other possibility is not to have Module:parameters strip whitespace, but to do it in Module:usex/templates so it applies only to. This business about leading/trailing whitespace being stripped in named but not unnamed params is a total kludge but it's the way Mediawiki works, and things like mwparserfromhell seem to know about this, so it may not be a good idea to change it.
