Flash programming parameters get violated all the time. Cypress, for
their PSoC parts, even specify the parameters as a function of voltage
and temperature. Everybody just shrugs and uses "safe" defaults ;-)

The question is just how much the Flash resents those violations ...

While under JTAG control, they bit-bang TDI to generate the core clock :-(
