I don't know if this is the appropriate channel to post something like this. If not, please redirect me to the right one.
Between yesterday and today we've noticed a new behavior in most of the O365 tenants. The new SharePoint feature “Site Pages”, which did not exist before, has started to be activated in all newly created Team Sites.
When this feature is activated, you cannot activate the feature “SharePoint Server Publishing” in the Team Site.
As this is something affecting critically all our cloud customer base and their productive environments, is there any way we can detailed info about why this behavior is applying now, if there is any way to prevent it and what are the implications of disabling the "Site Pages" feature?
We're aware that SPFx is rolling out and this feature might be part of the infrastructure supporting it, but we'd like to understand what are the real implications for O365 productive systems. This behavior started happening regardless of whether the environment has "Enable" or "Disable preview features".
