ahhhh good, youve seen sense ... if you want some fun, get an old PCB and just try desoldering a chip of a similar size- when your done have a GOOD look at that chip, and the state its legs (if u havent totally nuffed a few up already) and ask yourself how daft the question really is.
However as an idea its a good one to consider- if one company took the modular approach to the BX chipset who knows what the market would have ended up like- however modularising not only increases costs of production, but also changes the economic shape of their product in business terms. Change here will only happen if the company can see the $£YDm increasing thru it and will take planning and some risk
Currently throwing something away if its out of date is great for them, as we see here for the want of a slight alteration it means users have to replace their whole board, in effect selling them the chipset twice, (and are prepared to contemplate crime to get it

)
The market led change however will only be if a company can be convinced that there is a demand for a mod-mobo and take that gamble, perhaps a smaller company trying to grab a slice of a giants pie ... and the market reacts massivly to it as a product then other companies will have to produce solutions or loose share.
IMO any established mobo company will see it as a threat to $£YDm since it will cut off a significant amount of revenue currently coming to them. Instead it will go direct to the component manufacturers, with less in the mobo-co bank account, since a public demand for single chips will then appear. Of course Abrit or Saysus will sell you the chips as well but any good consumer knows its usually cheaper from source, and companies that were engineers delivering large batches of machine runs now have to have a sales office and staff nothing to do with their core business function, and deal with security differently, pilferage, thieft blah blah blah
While some chip companies might like the opportunity to supply the market directly the mobo companies will see it as a decrease in revenue, and react accordingly, things like making deals so only one type of controller works on their board, and tying in profits agreements and other corporate BS.
anyway dunno why I felt that was necessary to type, but is how I see it .... just have a go with that chip .... waffle over
