Apparently it is *has not been* an issue for *you* *yet*.  There are 
languages (like Python) that are compiled just-in-time.  Besides, neither an 
IDE nor a compiler can (always) recognize that foo["b0r"] is not foo["bOr"] 
(which really is not a far-fetched example as the O and zero keys are 
adjacent to each other on in keyboard layouts).  You do not want such an 
ambiguity to bite you later.
