Not ridiculous at all.A child might ask the question but you wouldn't have a decent answer. "Looking at other manufactures is a good guide to what is physically possible" is ridiculous.
If no-one offers what you ask it suggests of two things: it may be that what you ask for is commonly thought (by the manufacturers) to be not worth including, or it may be that no-one has found a way to do it in which case your expectations are unreasonable. Hence Scyrene saying it is 'a guide'.
There is nothing wrong with wanting something but to criticise a company for no other reason than you are ignorant of technical capability is flawed.
