Well akshuly. In ksh it is built into the shell, not gnu. That's how I
used it with the shells on HP-UX and Solaris.

Gnu readline is used in bc(1), for example, which lets me have have vi
mode there, but it has also caused the bc developers to lose the ability
to have blank lines from a user hitting enter twice.

I complained to bug-bc@gnu.org in 2022 about this and got back a reply
from Phil Nelson:

can't think of any other programs where he encounters readline()
