An IC does not guarantee that OP has to take your inputs into consideration.
That's true. But that also entirely defeats the purpose of an IC.
(not entirely directed at you, just as a more general statement)
The point of an IC is to determine interest in a product, it is literally impossible to please everyone who has interest. Changes to a product are at the discretion of the creator/designer, and technically an IC has no requirement to take input into consideration.
No one is slighted in the creation of a product unless that is specifically stated as a point by which the creator/designer set out to create something. Saying some minority group was slighted due to the removal or lack of a cap, is false and an unnecessary statement. Feeling like everything should bend to the will of the vocal minority is ignorant. (not arguing about what is and isn't a minority group, that argument is only toxic as shown in many threads recently)
If you feel a product doesn't support what you wish, move on with your life. Lambasting someone because they didn't support your specific need is uncalled for, and down right toxic to the community.
Sometimes there are reasons beyond your knowledge that cause decisions, such as layout support, to be made even if they will exclude a group due to said decision. If you are not privy to this knowledge or actual reasoning, first think logically and either decide to walk away or politely ask for reasoning, if they can't give you an answer to your liking (even if logical, just not want you wanted to hear), walk away rather than going after them to change their mind (one of the least effective methods to get someone to change their mind as it is more likely to make them not want to even more).
The creator/designer of this set has made decisions on the support, it may not be inclusive to all possible layouts but that is literally impossible to achieve and it may be unfortunate for those left out, but respect the creators/designers decisions even if they don't agree with you. If you still wish to not show respect, you may leave as you are only being toxic and are not being constructive to this community or this product.
SO on that note, this is an IC not a battleground where you wish to express your disdain for the lack of support for your layout (even if it is a standard...that is a subset of another standard), if you are not interested, leave and live a happier life rather than arguing. I want to see this community have fun and grow, not be up in arms over something that is honestly not worth the time spent typing or thinking. Enjoy the hobby, as hobbies are for fun, not for stress.
