It depends. Some people might want to have more time + energy working on side gigs/projects that they eventually want to turn into a full-time business.

If one's development doesn't matter and hasn't been rewarded, then it seems it's a moot point. Who cares if I stop improving if my job is one that I can coast at and still get paid? I'll never be a highly paid dev. Total comp is finally a bit over $100k this year due to a company wide bonus.
