[Feature request] Move initialization to Reset() for MonoBehaviour?

_Move initialization to constructor_ for `MonoBehaviour` is a bit meaning-less, rather, moving initalization to `Reset()` could be an interesting alternative.

Review the issue's proposal to move MonoBehaviour initialization from the constructor to Reset(). The payload names no files, tests, or entry points, so first determine where this initialization behavior is implemented and how the requested alternative should be defined before assessing completion.
