Interesting. Your "question" almost comes across as a statement on all the many reason why "functional" consultants will no longer be needed. Yet, your list is really just product features. And THAT is where I disagree with you. Any "functional" consultant worth their salt is not simply a "product consultant" but a process/strategy consultant who should have experience either across many industries or deeply into one (to a scary degrree at times! haha). They know how to make the "tool" meet the needs of the client.....and THAT will never go away. A good functional consultant will have accumulated a wealth of industry experience (either directly or through on-going education) that will make their knowledge always of value.
If you are talking about a "certified" consultant, then that is a different animal....one that can be usually described better as a "certified switch flipper"....they typically know they ins and outs of a product/tool...NOT an industry. This of course isn't to say that a truly knowledgeable consultant can't be a certified consultant as well, but is just that that population of consultants usually do not find any additional value in getting "certified" on a product over their accumulated experience (not to mention the cost of that piece of paper).
Now is that to say that "pre-packaged, pre-configured" solutions will not attempt at lessen the need of these specialists? No. This happens....and if you are old enough and get to live through enough of these cycles, you will find that this is par for the course......very specialized systems one day become out of favor for and "generic" one size fits all systems come into vogue for a bit until of course, customers decided that their differentiators are their customization of processes again. It is all just cycles. This one is no different than any before.
So make your own conclusions...but the very nature of your question sounds like you already have your own.
(*and for the record, I am a "techy" with enough functional knowledge to make me dangerous at best....so no "skin in the game" here)
