I don't think I've come across a reader which doesn't handle this
case. Almost all jpeg-in-tiff files use this mode, so you really have
to.

It's arguably a basic misdesign with tiff: writers are simple (you can
describe almost any pixel layout with a tiff header), but readers are
hard (you have to be able to read almost any pixel layout),

Anyway, this is the most common way of handling jpeg compression in
tiff, so I think you'll be fine.
