So for a contrasting anecdote, we've used SVGs for years in production on a high traffic site, using an automated Inkscape pipeline to turn text into plain paths, and it's worked perfectly
It's been a big success. The resulting SVGs are significantly smaller in filesize than PNG, and are crisp and readable no matter how the user zooms in.
The path conversion is a single inkscape command line invocation. It's worth doing.
If it comes out of a vector application, you likely don't want to rasterize it for distribution.
