Possible, but I was thinking more like there was air trapped in the
line that couldn't work out because of lack of flow through the new
hose, but the old, ugly hose still worked and allowed the system to be
bled properly.

I guess we'll have to wait for the OP to read this and post back...

I gathered that for 8 mos. the brake caliper was just "tied up out of the way" in
the fender well. If the hose was plugged that would allow pressure to continue to
go to the other brake in that circuit and keep the piston from being pushed out of
the caliper into the road. That description also makes it sound like "ugly" isn't
playing a big role in the decision process.
