Interlaced vs. Non-interlaced GIFs

I'm working on a software package that produces HTML documents and
GIFs (and other files) from a variety of input formats. Currently,
all GIFs produced by the package are interlaced, so viewers that have
the capability (e.g. netscape) can get the incremental display that is
nice to have over slow connections.

My question is this: is there any downside to always producing
interlaced images, or should I make it a user preference? For
example, are there viewers that would choke on interlaced gifs?
(Mosaic doesn't). Any other issues I should be aware of?

[Is this an appropriate question for this group?]
