I had a long twitter thread about this with some BSD developers,
https://twitter.com/landley/status/1127148250430152704
asked on the toybox list for opinions,
http://lists.landley.net/pipermail/toybox-landley.net/2019-May/010461.html
and became aware of this patch set when the android bionic maintainer pointed me
at news coverage of it
http://lists.landley.net/pipermail/toybox-landley.net/2019-June/010536.html
So there would appear to at least be interest in the concept.
(The conclusion I came to looking at it last month is is it can't be done
without kernel support, but if such support _does_ arrive I want to add it to
toybox.)
