Can I make explicit that the job is either grammatical description or discourse semantic description ?
One is concerned with classifying clause patterns and the other with discourse patterns.
Discourse semantic description explains functions of variations in grammar patterns such as types of Theme.
Typological comparisons might start with discourse semantic functions and ask how they are realised in grammar.

[1] To be clear, this refers to Margaret Berry's previous post (here) in which she redefines a clause function, Theme, in terms of two logogenetic patterns of instantiation: the selection of both Theme and Subject in the unfolding of text.
Here Rose misconstrues the lexicogrammatical distinction between this clause function and logogenetic patterns of its instantiation as a stratal distinction between lexicogrammar and discourse semantics. In doing so, Rose rebrands Margaret Berry's approach to grammar as Martin's discourse semantics.
[2] This is a bare assertion, unsupported by argument. To be clear, the "function" of logogenetic patterns of instantiation, such as varying the selection of Theme, is to develop the text.
Moreover, as demonstrated in detail here, Martin's discourse semantic notions of 'macroTheme' and 'hyperTheme' are the notions of 'introductory paragraph' and 'topic sentence', respectively, taken from writing pedagogy and rebranded as Martin's linguistic theory. Because they are concepts designed to help people write, rather than concepts designed to describe what people actually say, sign or write, they cannot shed theoretical light on actual Theme selection.
[3] Or perhaps, since it is the lexicogrammar that construes the semantics, and not the other way around, a Systemic Functional approach might be to ask what paradigmatic contrasts in meaning are being construed by paradigmatic contrasts in the wording.
