What changes are you talking about? Are you aware that Single File Components won't be removed? Asking because a lot of people on Twitter and Reddit seem to be under this impression that it's going away...

If you're talking about changing from the current v2 object syntax to v3 composition api might be hard indeed, then I agree with you... but I'm hoping we'll get some compatibility layer soon enough.

EDIT: According to Evan we'll get a "compat build" in the RC phase [1]
