These are items that are no longer obtainable and 99% of the population doesnt care about at all. For that 1% that wants to collect everything, the option is there.

It doesnt really bother me at all as long as they dont start putting really nice things on there that arent obtainable in game. That would be too much double dipping for me.

Just look at SWTOR: you have to pay a sub to have a decent experience and all of the endgame gear looks like trash while the cash shop vanity gear looks 100 times better, their focus in development is on the cash shop...

As long as it doesnt turn into any bs like that Im fine with minor things like minions and missed seasonal items.
