People sometimes see facees in the clouds, or in a water stain on a wall, or even a grilled cheese sandwich. We can debate whether those patterns mean anything without deciding. There are similar patterns in financial data where it's easier to test whether the patterns have meaning.
I have looked at constant capped volume (CCV), accumulated volume (ACV), intraday profiles, etc, plus some weirdo concoctions of my own. In the end, I didn't find any magic indicator that could find patterns that no others could. What really matters is whether the pattern is predictive. For now, I am staying with time bars because the data and backfill are easier to get.
