I think you have that exactly backwards. ONLY successful ideas are being debated more than 20 years after they are proposed. Only successful ideas spawn reaction and counter-reaction, which lead to its evolution - which you say is not happening, but certainly is, as evidenced by the tree of methodologies that branched from it.

In that respect (which might not be the one the coiners hoped for), capital A agile has been extremely successful.

If it was successful, it would be so normal that there would be no argument about it. It would be taken for granted as the platform which other improvements are built on. It would be like water to fish. That is not what I see.
