IMHO, 16bit will by useful even in ARM platform with low RAM
resources.

May be sometimes we will found "configuration manager": we will choose
options, and receive answers about resources requirements. And each
customer will personally decide, what is more important: additional
RAM (and separate space for each task, stability) or price.
