How _could_ the kernel know what some user process thinks constitutes
uppercase or lowercase?  And even if you grant that, arguendo, which
process's idea of "printable" should it use?

The only way I see to make this work at all is for the kernel to have
its own idea of what constitutes printable, lowercase, uppercase, etc,
and have some way for stty to load those tables, or at least switch
among a few compiled-in tables.  (Perhaps some of the commonest, such
as US-ASCII and ISO 8859-1, should be compiled in, with an escape so
stty can cause the kernel to allocate a block of memory to hold
arbitrary tables in case of something more esoteric.)
