This is a good question and something I have been wondering about recently
while working on some performance improvements for Streams.
In general terms, there is a cost to having wikitext in CSS tiddlers when
refreshing the styles in refreshStyles()
However most of the time this is negligible compared to the time taken by
the actual rendering process.
This might make for a good dev discussion on Github.
