Open up the german double s (ß)

[charakterziffer]

For me as a German reader it looks very unusual when the ß is closed at the bottom, it’s a very rare design solution (among the 150 font families on my computer only the blackletter Grenze Gotisch and the constructed URW Gothic do the same. Was this a conscious decision?

The uppercase variant (ẞ) is open at its base, would you please also unclose the lowercase ß, too?
