If we can enable a holiday period for our personal environment, it can save us trouble and inconvenience of having our apps deleted.

Thou to ensure this is not being abused, when we set the holiday, there must be a start and end date. And maybe some validations, eg not more than 2 months etc...so that we will not be able to set for 1 year or something.

Of course, the time period, will not be able to please everybody.

Then after this holiday period ended, the existing control can comes in, eg. if not logged in for 2 weeks, then deactivated and eventually removed

Think this is good, as I sometimes do go on a slightly lesser than 1 month holiday, and will not be able to log in.
