There are good reasons to prefer shutdown to sleep, and for wishing to avoid the several-GB dump file into the SSD each time it sleeps. Of course, users that prefer the iOS way of doing things, will find this new MBP behavior more familiar, as it makes the MBP feel "more iPad" and "less Mac". It seems pretty obvious that all these changes, trying to make it difficult that you leave your MBP in shutdown status, follow the strategy of ensuring that the iPad is the Mac of the future. I won't be an Apple user anymore when that time arrives, as with this new MBP I'm installing only software that is available in other OSs in addition to MacOS, and I'm preparing everything for being ready when the moment of no return arrives (and it will). Hopefully, with the way I'm installing software and data in my new MBP, my switch away from Apple will be so easy as when Apple moved from PPC to Intel: They were already building OSX in both CPUs from the beginning. I'm planning (and already executing) something similar, from today on.
I'm not sure where you're going with here... As I mentioned earlier the technology industry in general has moved away form Shutdown and to preferring Sleep. This change actually started many years ago well before we were knee deep in the Phone Era. It makes a lot of sense as users don't really need to micromanage their technology as much anymore.
We have lots of RAM and Operating Systems have gotten extremely good at memory management. Including smartly paging to disk and preloading application data. Impressive hardware enhancements have arrived as well like SSDs and deep sleep support in CPUs and other components. Windows 10, as I mentioned earlier, doesn't even shutdown its Kernel anymore and instead hibernates it and resumes it even when a user clicks "shutdown".
Also, worrying about wear on an SSD is nonsense now. They'll handle far more writes than almost any user can realistically push through them.
If a user needs to explicitly force the system to shutdown, such as not needing to use it for a long time and wanting to preserve the battery life, they can still do so. Nothing in the new MBP changes prevent this.
Shutdown the MBP, close the lid, put it away and it will say off and in a true shutdown state...
But that should be a rare thing as with 30 days of battery life in sleep mode users are able to appreciate the new models benefits.
There may be reasons to be unhappy with how computing is changing, but this isn't one of them.
