Rolled up armadillos can be pushed. This looks very unnatural and strange. It is also inconsistent with the camel, which cannot be pushed when sitting down.

Steps to reproduce:

1. Create a world with the 'Armadillo and Wolf Armor' experimental toggle enabled.
2. Run '/summon armadillo'
3. Sprint near the armadillo so it rolls up
4. Attempt to push it and see that it moves

You can also summon a camel, wait for it to sit down, then try to push the camel and see that it will not move.
