Blindly trusting webgl is even more unwise than blindly trusting js, because most stacks are accelerated via passing third-party data to shoddy native code. If you're actually putting content on the world-wide web (not just a game that's useless without interactive behavior) js+webgl should never be the only rendering, but I fear that most authors don't care about this.
