I noticed only the outer box comes with a tamper-evident seal and the inner/main box is only bubble & shrink wrapped!
I am not worried about tamper-evident seals at all.This is just superficial stuff that can be replicated and it is not offering any real protection against anything, it's just providing false sense of security.
Unfortunately some custom offices open the sealed package. The device comes with or without firmware?
Sometimes I think that sole exitance for custom workers is to ruin and open sealed packages that are coming to customers 
Every time I order something online, especially overseas, I am trying to find alternative way for shipping, maybe friend delivery or me traveling to better location to pick up package.
I would prefer to receive device without firmware install and do everything manually, but most likely you will need to update firmware soon anyway.
As of right now, honestly nothing. I will look into something simple, without tons of bloat introduced by suspicious (read: Google et. al) frameworks that I can compile myself, in the future.
That would be cool to see 
I am currently thinking about good apps we can use for smartphones, related with Bitcoin, and open source wallets are big part of this.
This is not to be used for holding big amount's of money, more like pocket money and something used for p2p trading in person.
One interesting thing I noticed recently is that Graphene OS with Pixel6 phone is using twelve words backup option and I think this could be BIP39 compatible but I am not sure.
