Perhaps it can also be renamed "SHP" (strict homepage processor)

Why would anyone prefer a tool dead set on undoing their productive investments with each new release? Decisions like this are a massive red flag. It doesn't allow the feature to be removed (interpolation still exists and isn't going away), I doubt it simplifies the code much, it just breaks existing projects out of essentially a stylistic preference. That's not a tool I'd ever want to depend on

Did you read the full RFC? It's not strictly 'stylistic preference' as each version has slightly different capabilities and there's potential ambiguity between some of those capabilities.
