MusicXml : export of text styles

At present, when text styles are applied only some are exported - this applies notably to lyrics.
This is great.

However, this is not done for stave text notably (at least this is where my tests concentrated on).
What do I mean ?
It is possible to change the alignment of the stave text by going into the text properties.
However, this is not exported to MusicXml.

Are there any plans to enrich the MusicXml export with this type of information - not just alignment, but other formatting information such as colour, font style, weight and size, when different to the default ?
