Usually... It works like airplanes. Some people see Tomcat and know immediately what it refers to. Others prefer the numeric F-14. I still remember NATO codenames from 40 years ago, without the letter/number. Sidewinder, for example. I have the issue you describe with Ubuntu and (less so) Debian codenames and also with Android codenames. With Ubuntu though, the number is descriptive, like Russian tanks (T-90 etc), so using it is worth more.
