So here's another tangent, but has it been considered to add an option to the printf builtin to print to a given file descriptor, rather than stdout? If printing to a number of different file descriptors in succession, such an option would appear to have all the same benefits as read's -u option.
It doesn't actually save anything; it's just syntactic sugar. Since
`printf' uses stdio internally (as opposed to `read', which uses the
supplied file descriptor directly), you're still going to have to dup2
it internally somewhere. dprintf could do some of the work here, and bash
has a replacement for systems where it's missing, but that's more than I
want to change before bash-5.3 comes out. Maybe after that.
