Oh, no they were added in 1.31.0.

The Regex class was always a bit "wrong headed" and not very good design, 
most people were using the templates directly anyway, and once these were 
accepted for standardisation there was no reason to continue supporting the 
old interface.

There's no difference in performance between them, they all call the same 
routines internally.
