[Documentation] Default values on struct members

[NoxWings]

https://shader-slang.com/slang/user-guide/conventional-features.html

On this page there is a note mentioning

Note
Slang currently does not allow default values on struct members, but we intend to support them in the future.

But then later on
https://shader-slang.com/slang/user-guide/convenience-features.html

Member Init Expressions
Slang supports member init expressions:

struct MyType
{
    int myVal = 5;
}

Aren't they referring to the same thing? should the docs be updated?

The current semantics around initializers is not consistent or sound. There is an ongoing work to clean this up, and this will be fully supported once that work is complete.

See PR: #5215
