I don't see that anyone has mentioned the demonstrated
crosswind component, which is in the P.O.H. for certified aircraft. You
may do better, but that's the best number the manufacturer achieved with a
new aircraft and a very good pilot. If the calculated crosswind based on
the wind speed, direction, and available runway exceeds the DCC for your
aircraft, it's cause for at least caution if not an outright scrub of the
flight.

That statement, for small Part 91 aircraft, is not the case.

The demonstrated crosswind component is merely what the wind happened to be
on some day when the crosswind was blowing at least strongly enough to meet
certification requirements. The 14 CFR 23 requirements are that this value
be at least 0.2 Vso.

========================================
§ 23.233 Directional stability and control.

(a) A 90 degree cross-component of wind velocity, demonstrated to be safe
for taxiing, takeoff, and landing must be established and must be not less
than 0.2 VSO.
======================================

It is not even close to being a limitation.
