Impressive Integration:I charged-up my old iPad (a Series 2, I believe?) which runs on iOS 9.3.5 and found that the new
Lr CC does run on it even though Adobe's listed platform-requirements firmly state that it won't.
The iPad took a while to pull my images from the Cloud (I have 60,000 or so of them sitting on the Cloud!) and all of the editing tools in Lr CC are fully operational on my iPad should I ever want to use it.
I edited a photograph on the iPad; synced it back to the Cloud; fired-up
Ps CC 2018 . . .
and there is the image (which I had only just edited) sitting on the Start-up/Welcome Screen and also in the Search Panel.
Click on it and it opens in ACR with all of the ACR Sliders already in place to show the image in exactly the way that it looked in Lr CC on my iPad.
Then I opened
Lr Classic CC.
Same thing: file has been updated and the Sliders are all set in the right positions to display the photograph to match the changes which I made in Lr CC (iPad).
THIS is the level of "Integration" that many people need!
And the edited image is immediately available for use in all of the other Adobe programs which I use.

There is no requirement to subscribe to or purchase any particular brand of software
IF you choose to buy an Adobe Creative Cloud Subscription you get four different programs and ways to process your RAW images; and you can use them interchangeably whenever you want to — depending on what is most convenient at the time.
In addition, the
optional Cloud storage gives you access to any of thousands of your images from wherever you may be on the Planet at that moment.
The data stored on the Cloud is very compressed (basically a Smart Preview and the text in the metadata) so it uses about 1 MB per image. For the basic $10, a subscriber gets (in addition to the use of the software) 20 GB of free cloud storage which is sufficient for a lot of 1 MB images and will probably be sufficient for most people.
If you use Lr Classic CC, you would choose which particular files you wanted to Sync to the Cloud if you needed to stay within the 20GB limit.
(Put the selected files into Collections and Sync just those particular Collections to the Cloud.)

Concerning "Indefinitely": that means for an undefined period of time.
Anyone who construed "Indefinitely" to mean "Infinitely" was being un-realistically optimistic!!
