Nouu I knouu uuhy it’s called “double U”.

Also, yogh looks too much like the Arabic numeral three, so it sort of makes sense why they got rid of it.

I believe Œ is still used in French (though it doesn’t count as part of the alphabet), but I just spell it as OE since it just looks so ugly. Æ looks way worse though, and Icelandic still uses it.
