  Present day quantum field theory (QFT) is founded on canonical quantization,
which has served quite well, but also has led to several issues. The free field
describing a free particle (with no interaction term) can suddenly become
nonrenormalizable the instant a suitable interaction term appears. For example,
using canonical quantization, $\varphi^4_4$, has been deemed a ``free" theory
with no difference from a truly free field [1], [2], [3]. Using the same model,
affine quantization has led to a truly interacting theory [4]. This fact alone
asserts that canonical and affine tools of quantization deserve to be open to
their procedures together as a significant enlargement of QFT.
