Why Alpine Edge?

[ashleysommer]

I understand that at one stage Alpine Edge was the only version to offer the mongodb package.

However Apline release v3.8 has mongodb:3.6.7-r0, and the newest Alpine v3.9 has mongodb:4.0.5-r0.

Would you consider releasing versions of this container based on Alpine v3.9 for those who prefer to not use Edge?
