Can you please be a bit more specific on what you mean with "breaking"
in this context? What exactly is broken? Just active scanning (i.e.,
sending the Probe Request frames)? Or scanning in general (i.e., not
getting any scan results at all)? Or something else?

For most cases, it is likely fine to omit extra IEs from Probe Request
frames, but this does break some cases like WPS PBC and P2P.
