^This + one of the key features of an RPG like this is choice, and even if only 0.1% will make a certain choice the other 99.9% get a contrasting choice to what they made. What is the point of having choice if you only include choices that everyone most likely will make?
Time. No studio has unlimited time and resources. Decisions have to be made to exclude some things in order to produce a product that appeals to a large audience at a reasonable time.
So yes some 0.1% of the population will be disappointed their pet customization is not included but hopefully the entirety of the game is good enough they will buy the game regardless. This isn’t an all or nothing choice.
