In my opinion, yes. These days, you'd need a good reason to use IDEA
rather than AES, CAST5, or even 3DES. When you add in the fact that
IDEA actually costs money (heresy!) and nearly every competitor is
free, it becomes a fairly easy calculation to make.
In the context of OpenPGP, the gradual abandonment has already
happened. The usage today is non-zero, but negligible. The only
reason the IDEA discussion comes up here (usually once or twice a
year) is that PGP 2.x used it back in the 1990s.
