With all due respect, the reasoning behind this reason for crippling Photos doesn't add up. Many will deduce and speculate one or more alternatives like:
- This was a mistake or accidental omission that slipped through requirements testing. The Libraries functionality changes in 8.1 may have an adverse ripple effect on other functionality.
- New contractual obligations to services like Facebook warranted crippling.
- Windows 8.x design is eroding away from a unique, market-leading integrated UX and returning to a model of "apping in and out" to perform mundane tasks (like viewing photos).
- This reason is actually incorrect and synthesized to provide a quick answer to the community.
Regardless of wild speculation or implications to Photos, some will be watching this under a larger scope, perhaps as a harbinger of things to come.
Good luck with the journalists!
