Please allow PIN unlock in 1P8 Android

Out of curiosity, how would PIN Unlock work?
- After reboot (or logout/login; e.g. Chromebook), I'd want to enter my 1pw before the PIN is automatically activated. [But maybe a Setting would allow users to disable this.]
- After X number of failed attempts, I'd want the PIN deactivated; such that I must enter my 1pw before the PIN is activated again. [User's may want a Setting to control X.]
- Would there be an option to have the PIN timeout? e.g. Y mins/hours/days. i.e. after the timeout, the PIN would be deactivated; after entering my 1pw it would be activated again.
- Would there be a way to quickly select PIN deactivate; i.e. I don't want to wait for the timeout or I'm not using the timeout feature.
- Would there be a minimum PIN length? e.g. 4 or 6? I assume the maximum length would be large; e.g. 20.
- Would setting up the PIN (and/or Watchdog) warn against a poor PIN? e.g. 1111 or 1234
- Would the PIN only be numeric, or can I have a character PIN? e.g. s#8J

I have an interest in the PIN for the Chromebook, since 1PW does not support biometrics on the Chromebook.
