I think we pay attention to "dumb" when deciding if pager is useful and if
we can do color, but I do not think we check anything beyond "is it a tty"
when deciding to show progress or not.  The only thing we do differently
for "dumb" terminal is if we use ANSI clear-to-eol escape sequence or fill
with a run of SPs to overwrite trailing part of a line, and we assume even
dumb terminals know how to do a carriage-return.
