AMSmath subequation enviroment

I hate to be a bother since I know that there are many issues and a lot of work to be done, but there is one thing that I would love to have for mathjax. Will there be support in the future for the AMSmath subequation enviroment? Has it been considered yet or it is too hard to implement at the moment? For now, my latex documents contain blocks like this:

\begin{subequations}
 \label{eq1}
 \begin{align}
  a & = b \label{eq11} \\
  c & = d \label{eq12}
 \end{align}
\end{subequations}

I can get rid of the subequation enviroment and just have a new number for each of the subequations but now in my text I have to get rid of every reference to the main label eq1. Is there any workaround for now to the lack of support to subequations?

No implementation files or tests are named. Start by reviewing MathJax's existing AMSmath environment handling and its equation-label and reference behavior; done means supporting the subequations environment while preserving references to the parent label and individual subequations.
