It's not so much that it's gatekeeping, but there's a big difference between writing bloated Electron applications with few, if any, constraints vs. writing Ada in an extremely constrained environment where there's memory constraints and other overhead that doesn't exist in the web development realm. If the former fails, a user gets slightly annoyed. If the latter fails, people die. One takes way more skill/training than the other. To treat the two on the same level is insincere at best.

It doesn't take substantially different training beyond recognizing that one is applying a different tool in a different environment.

It's all programming. Different patterns, stacks, and pressure to test? Yes. Fundamentally the same work loop, however. I'd advise against raising one level of endeavor over another. It seldom produces substantive or useful conversation.
