For sure, especially for fonts geared towards programmers and technical uses where numbers and symbols matter a great deal. A person could probably figure out that he110 is "hello" but as identifiers, he110 and hello are not interchangeable.

yeah, that's where all those huge font cataloging websites could shine (and also allow you to filter fonts based on this, eg, all zeroes should have some mark in the middle not be confused with the letter O), yet they settle on some bland pangram
