I think I read somewhere that excessive stylesheet tiddlers can impact performance. Each needs to be rebuilt and reapplied on every refresh of the wiki.
I, too, have a system that transcludes a bunch of tiddlers all destined to become part of a single actual stylesheet tiddler. While it’s “clean” and beneficial from a code management point of view, I’m no longer so happy it was the right move in terms of performance.
