why suspend operator fun getValue not supported in kotlin?

Why following signature gives Unsupported [suspend operator "getValue"] compilation error?

suspend operator fun getValue(thisRef: Any?, property: KProperty<*>): T

Is it because of any technical limitation?

The getValue operator is for implementing the getter of a val, and there is no such thing as a suspend val -- only a normal val.

A suspend fun can't be called directly from a normal function, like the implementation of a getter -- so this getValue can't be used for its intended purpose. Kotlin warns you of that by giving a compile error on an attempt to create a suspend operator fun getValue.
