This stinks of no-one-knows-what-the-fuck-they-are-doing-itis, a common problem in the software engineering community. When mixed with a deadly dose of sunk-cost-fallacy-itis and project-death-march-itis, the only way out is adding more JavaScript until it creates a singularity from the accumulated mas and sucks the project into oblivion.
Trying to fight one of these off now. We don't need a fancy shit ass UI. We just need stuff that works and is simple. But plenty of one-trick pony developers and architects who build complicated mechanisms out of piles of nodejs and microservices which merely consume time, energy and attention and delivery sweet fuck all ROI.
