Yes, nobody is denying that "every feature is an eternal maintenance price"

But the maintenance price of such basic features is absurdly low. Seriously, we're talking about a basic dictionary lookup. We're not talking about massive, expansive features that will require many hours of maintenance.

Anyway, if you don't use a dictionary at all, even while reading - and you think a "handful of users" use them - then this conversation probably is not going to go anywhere.
