There might not have been speculation then, but there sure was micro-architectural leaks. See my FOSDEM talk on this: https://archive.fosdem.org/2022/schedule/event/z80/ (and it barely scratches the surface).
Of course this does not matter on a single-user computer that does not run arbitrary untrusted code from the Internet.

so surely we should be using 6502 processors then

famously there are fewer transistors in a 6502 than there are pages in the x86 documentation. It's actually possible for one person to know what each transistor in the 6502 is doing and audit it.
