I notice that FunctionQuery says “Note: This API is experimental and may change in non backward-compatible ways in the future”. Is this still true? I mean, sure, any of the APIs could change, but hasn’t FunctionQuery been relatively stable long enough to warrant removal of the “experimental” stigma?
