We've been through that so many times. When UML arrived (and ALM tools suites, IBM was trying to sell it, Borland was trying to sell it, all those fancy and expensive StarTeam, Caliber and Together soft), then BPML and its friends arrived, Business Rule Management System (BRMS), Drools in Java world, etc.

It all failed. For a simple reason, popularized by Joel Spolsky: if you want to create specification that describes precisely what software is doing and how it is doing its job, then, well, you need to write that damn program using MS Word or Markdown, which is neither practical nor easy.

The new buzzword is "spec driven development", maybe it will work this time, but I would not bet on that right now.

BTW: when we will be at this point, it does not make sense anymore to generate code in programming languages we have today, LLM can simply generate binaries or at least some AST that will be directly translated to binary. In this way LISP would, eventually, take over the world!.
