  We discuss how the quantum-critical-point scenario for high-T_c
superconductors with density-driven charge order or stripe formation finds
support from recent EXAFS experiments. Our phase diagram has the interesting
feature, which is also suggested by the EXAFS experiments, that some cuprates
may not show well-formed stripe phase. We also consider the extensions of the
scenario to include the interesting possibility of first-order transitions
which call for further experimental and theoretical investigation.
