That is the only serious alternative, as far as I'm concerned.

Agreed. And they are/were intended for human consumption rather than
to be processed by a machine, which explains some of the oddities in

Basically, with plain TeX mode the 8bit stuff should be off. With
latex, my understanding is that people want it on, and same for
context. But in both of these cases, only eight-bit input will get
you eight-bit output.

You'd have to write a 7bit.tcx that actively suppresses printability
for all but the range 32..127 inclusive. Easy to to with the new
code, but it would have to be done.

There are currently _no_ settings for this in texmf.cnf.
