Have you considered adding oldstyle figures?

[MartynKramek]

Hello Rosetta and contibutors,
I suppose that lack of oldstyle figures in yrsa-rasa is deliberate, but I think incorporating them would enrich the design greatly, and make it look even more beautiful and have more humanistic appearence in running texts containing dates or other arabic numbers.
I'm sorry I'm not a type designer, and I'm just lacking basic skills to contribute to your project.
That is why I'm asking, if according to you that would make sense to include this set of ten glyphs, to make the design complete, Having OSF seams to me quite basic.
What do you think?
