I guess this is the balance between how much less you pay for standardized tools and tech (and R&D), and how much more for all the BOM extensions required. TTM may be important too, favoring using of-the-shelf techs. On the long run, and with big quantities, the balance might actually justify the custom-made.

However, it is with the big quantities deployed that the issues of firmware upgrade -- reliability, ease of use, security -- become really serious, tipping the balance again towards the standard tech.
