Broken faith shield and Purifying flame

Hey, so... I was wondering something about a possible interaction between purifying flame and broken faith shield. I don't know what kind of interactions are intended. So, as we know, broken faith makes you create profane ground instad of consecrated.

When using purifying flame, it does indeed create profane ground, but as far as I can see, there aren't any shockwaves happening. This is likely because the shockwaves look for consecrated ground, and profane ground does nothing. (Then again, I play on low res, so I might be missing it)

I was wondering if purifying flame will ever be expanded upon to allow interactions with profane ground?

On that topic, what about the Inquisitor concecrated ground ascendancy path? I think it would be cool to have some kind of thing for it to use profane ground, as by the descriptions given they would be canceled out by the shield.

Or entire new mechanics revolving around profane ground that could contribute to build viability and make interesting effects.

Just some things I was thinking about.
