Some languages, such as Kiowa, use bowl-struck variants of the letters Ƀƀ Đđ Ǥǥ. DejaVu Serif provides a bowl-struck stylistic variant for Đđ Ǥǥ, but not for Ƀƀ. It would be nice if the option were available with all three pairs of letters, for full support of Kiowa and similar orthographies.

I'm not sure what I'm allowed to upload. See Unicode proposal L2/25-067 for illustrations.[https://www.unicode.org/L2/L2025/25067-bowl-struck-variants.pdf]

PS. DejaVu alt cap Ǥ has a nice, clear half stroke, reflecting what is seen in hand-designed book covers. It's nice that Adobe noticed this detail.
