So even use of, say half of them, for strings of, for example 80 bytes
per string,
is 'de minimus'.

Seems to be a cheap enough course to just double 'em, then, and not
complicate
the build with yet-another flag.

FWIW, as they can be overlaid and also function well as accumulators, I
have yet to need more that half of either type, despite running a
'dual-track' pre-scanner progressive scoring system, (protocol violation
count, format error count, etc.).

- so am not expecting to resort to nyble-packing, greyscale, or bitmaps,
even at the current limits ... ;-)

Best,
