Yup, casinos are always checking for every idea where gamblers might choose them from all the competitors around, they are actively checking which services and perks that they can provide in order to attract more people to play and use the site, I think what you mentioned are things that affects how gambler choose which site they will be playing.
Along the way, gambler always have an option in case they are not comfortable or they don't feel that they like to continue playing
with the site they are using, they can try other services from other gambling site.
This is always done by casinos so that there are no customers who feel dissatisfied so they choose another casino, even as you said the casino will outperform the services and all the features that are owned by other casinos so that customers still feel comfortable and loyal, even so they can get more new players.
Yes, what I mentioned is the way for gamblers to choose the casino they will play at, but this method is no less important than the most difficult features when choosing a favorite casino.
The choices and comfort that gamblers have will of course be different so that casinos can only provide the best which implements all the best features that can make gamblers stay comfortable and not move to another casino.
