Disable notifications per-space (and perhaps per-page too)

I want to add my voice to the many others who have expressed a desire to have more fine-grained control over notifications on a per-space (and perhaps per-page too). This is to support the situation when a private space is set up to contain sensitive information (passwords, private keys, etc.) and we don't want page edits to trigger email containing the sensitive information (as that will open up many more ways in which that info can be sniffed or hacked by 3rd parties).

The ideal solution will implement the same Notification Scheme setup available in JIRA (where each JIRA project can be assigned its own notification scheme... similar, each Confluence space should have the ability to be assigned its own notification scheme also.

Many others have asked for this before:
CONF-174
CONF-29996
CONF-27567
CONF-28326
CONF-30826
CONF-33698
CONF-35985
CONF-41394
CONF-33887

I think this is a basic/fundamental functionality for a wiki software designed to support multiple spaces with different access rights.

Thank you.
