I've seen plenty of NI content talking about Shared Variable drawbacks and downsides, and I know plenty of users who will happily use just about any other solution. Shared Variables work great in some very specific use cases and moderately to poorly in other scenarios.

My understanding -- and this is second hand data without me understanding the details -- is that this isn't a technical issue to be fixed. It's a limitation of the nature of the shared variables and what they are designed to do. They validate network connections up-front, part of their mandate for use in process control. If you're building an industrial factory controller that is going to run without stopping for months on end, who cares about a 60-second boot time? What you care about is that when your code hits that first node, its running as smooth as it can (least jitter) and knows its data is ready to go.
