 Replying to [comment:1 tomfukushima]:
 > Checking performance impact: Is this code that we are adding the changes
 to executed once per feature drawn, or once per symbol definition used by
 the layer?

         The code may be executed more than once per feature if the
 symbolization contains more than one text primitive. I'll point out that
 the additional string copy is probably less expensive than the expression
 evaluation which is happening with the same frequency.
