I just made RT-21096 visible. We have no concrete plan to implement
this, but David Grieve might wish to comment.
From previous discussions, it seems like Node.impl_getMatchingStyles() is
going to be made a public API.
The lastest reference I can find is in June 2013:
In the source code, the ticket number for this is RT-21096, but I am not
able to view it in JIRA.
Just wanted to know what is the status of this. Is it still planned to be
made public and if so when?
