Lunacy is too strong! I think the average mobile app developer has no business thinking about radio optimization. They should however be spending lots of time thinking about cacheing and minimizing interaction with servers. Developers in general have gotten too comfortable with unnecessary traffic on Desktop machines. There are too many devs who have been focused on speed as the limiting factor for mobile apps, when it fact should be cost. The end user is paying not only to acquire your app, but also to use the mobile provider's transport. We should take every opportunity to reinforce the importance of minimizing mobile traffic to only what is necessary. Just because you can use a 4G connection to move a ton of data doesn't mean you should.
