Is there in fact general agreement among the devs that the criteria for
deciding when to use sRGB primaries instead of UserRGB primaries is
approximately as follows?

the first thing we should do is to
annotate all the operations which are broken when done with sRGB

In other words, you will make a list of all operations that "don't work" in unbounded sRGB, and then you will convert from unbounded sRGB to UserRGB for those operations, and then back to unbounded sRGB. Good luck with that.

Using a fixed linear RGB format instead of userRGB is what for some
operations will provide the consistent results for the same property
values / slider positions.

As a maxim for guiding GIMP development, "consistent results for the same property values / slider positions" reflects a profound failure to understand the nature of RGB image editing and can only lead to bad code.
