I was wondering what the relationship between the devel and master
branches was. I saw that you turned MULTIPLE_COPROCS=1 on by default
under devel, but haven't touched the somewhat more substantial changes
that sounded forthcoming, from that whole conversation. So I take it
MULTIPLE_COPROCS=1 will be enabled in bash-5.3 but other potential
changes would come later?

Do you keep a list of TODOs and things under consideration somewhere?
